Building Dynamic Web Applications with Entity Framework Core in ASP.NET Core
Jun 24, 2024

Introduction First we need to understand why we use ORM tools instead of manually managing data access. Manually managing data access involves writing code to interact with the database directly using languages like SQL. This approach can lead to several challenges: Boilerplate Code: You need to write repetitive code for common operations like connecting to the database, executing queries, and processing results. This can be time-consuming and error-prone. Error Handling: Manual error handling for database interactions is complex and requires careful checking for potential issues like SQL injection attacks or data type mismatches. Data Model Mapping: You need to manually map data between your application objects and the database tables. This can be cumbersome and error-prone, especially for complex data models. ORM Tools as a Solution: Object-Relational Mapping (ORM) tools like Entity Framework Core (EF Core) address these challenges by providing a layer of abstraction between your application and the database. Reduced Boilerplate: ORMs automatically generate most of the code for data access tasks, freeing developers to focus on application logic. Simplified Error Handling: ORMs handle common errors and data type conversions, improving code reliability and security. Automatic Data Mapping: ORMs map your application objects (like classes) to database tables, reducing the need for manual data model manipulation. Improved Portability: Many ORMs support multiple database providers, allowing you to switch databases more easily. Enhanced Maintainability: Changes to the data model can be reflected in your object classes, simplifying code updates.                  Overall, ORMs like EF Core streamline data access in web applications, promoting faster development, better code maintainability, and reduced risk of errors. What is EF Core? : Entity Framework Core (EF Core) is a tool that simplifies working with databases in your .NET applications. It acts as a bridge between the object-oriented world of your application (think classes and properties) and the relational world of databases (tables and columns).   Benefits of using EF Core for data access:  Increased Developer Productivity: EF Core significantly reduces the amount of boilerplate code required for data access tasks. Developers can focus on building the core functionalities and business logic of the application instead of writing repetitive SQL queries. Automatic data model mapping eliminates the need for manual data manipulation between objects and tables. Improved Code Maintainability: By centralizing data access logic in EF Core, your code becomes cleaner and easier to understand. Changes to the data model can be reflected in your object classes, simplifying code updates. Type Safety and Compile-Time Checks: Defining your data model with classes and properties in EF Core enforces type safety, helping catch errors early in the development process. Support for LINQ: EF Core allows you to use LINQ (Language Integrated Query) expressions for querying data. LINQ syntax is similar to working with objects directly, making it easier to write and understand queries. Improved Code Readability: Separating data access logic from business logic leads to cleaner and more readable code. This makes it easier for other developers to understand and maintain the code base.   Step-by-Step Guide with Code Examples  This guide walks you through creating a basic Web API in ASP.NET Core that uses Entity Framework Core (EF Core) to interact with a SQL Server database. We'll build a simple blog example with functionalities for managing blog posts. Setting Up the Project:  Open Visual Studio and create a new project. Select "ASP.NET Core Web API" as the project template and give it a suitable name (e.g., MyBlogApi). Choose a suitable .NET version and click "Create". Installing NuGet Packages: Navigate to "Manage NuGet Packages..." & Search for and install the following packages Microsoft.EntityFrameworkCore Microsoft.EntityFrameworkCore.SqlServer These packages provide the necessary functionalities for EF Core and its SQL Server provider. --

Understanding Different Types of Switching in Table Partitioning in Microsoft SQL Server
Jun 21, 2024

Introduction We focused on optimizing database performance and manageability, it’s important to understand the nuances of table partitioning in SQL Server, including partition switching. Partition switching is a feature in SQL Server that allows for fast data movement between tables and partitions. This blog explores the different types of partition switching and their applications in SQL Server.   What is Partition Switching? Partition switching involves moving data between partitions or between a partition and a non-partitioned table without physically copying the data. Instead, metadata pointers are updated, making the operation extremely fast and efficient. This is especially useful for data archiving, loading new data, and maintaining large datasets.   Types of Partition Switching 1. Switching Between Partitions in the Same Table Switching data between partitions within the same table can be useful for reorganizing data or when performing operations that require temporary partition rearrangement. Example: Suppose you have a table SalesData partitioned by month and you need to move data from one month to another. -- Switch data from partition 2 to partition 3 ALTER TABLE SalesData SWITCH PARTITION 2 TO SalesData PARTITION 3; 2. Switching Between a Table and a Partitioned Table This type of switching is typically used for bulk loading or removing data. You can switch a partition of a partitioned table to a non-partitioned table (and vice versa) to quickly load or archive data. Example: Loading new data into a partitioned table SalesData from a staging table StagingSalesData. -- Ensure the staging table matches the schema of the partitioned table CREATE TABLE StagingSalesData ( SaleID int, SaleDate datetime, Amount money ); -- Switch the staging table data into the partition ALTER TABLE StagingSalesData SWITCH TO SalesData PARTITION 1; 3. Switching Between a Partitioned Table and Another Partitioned Table This involves moving data between two different partitioned tables. It’s useful when dealing with different data lifecycle management scenarios, such as archiving old data into a separate historical table. Example: Switching data from a partition in CurrentSalesData to a partition in HistoricalSalesData. -- Both tables should have the same structure and partition scheme ALTER TABLE CurrentSalesData SWITCH PARTITION 2 TO HistoricalSalesData PARTITION 1; 4. Switching Data Out of a Partitioned Table This is used to remove data from a partitioned table and move it into a non-partitioned table for further processing or archiving. Example: Switching data from a partition in SalesData to a table OldSalesData. -- Ensure the target table matches the schema of the partitioned table CREATE TABLE OldSalesData ( SaleID int, SaleDate datetime, Amount money ); -- Switch the data out of the partition ALTER TABLE SalesData SWITCH PARTITION 1 TO OldSalesData; Guidelines for Partition Switching To ensure smooth partition switching, consider the following guidelines: Schema Matching: Ensure that the schemas of the source and target tables match exactly, including constraints and indexes. Partition Alignment: The source and target partitions must align correctly based on the partition function. Check Constraints: Check constraints on the tables must be consistent with the partition boundary conditions. Minimal Indexes: Avoid using non-aligned indexes on partitioned tables to ensure efficient switching. Benefits of Partition Switching Performance Efficiency: Since partition switching involves metadata operations rather than physical data movement, it is extremely fast and efficient. Minimal Downtime: Enables quick data loading, archiving, and reorganization with minimal downtime. Data Management Flexibility: Facilitates flexible data management strategies, allowing for efficient data lifecycle management. Conclusion Partition switching is a powerful feature in SQL Server that enhances the performance and manageability of large datasets. Understanding the different types of partition switching and their applications allows you, to implement efficient data loading, archiving, and maintenance strategies. By leveraging partition switching, you can ensure that your SQL Server environment remains robust, responsive, and well-organized, ultimately supporting your organization’s data management goals.

Comparison between Minimal APIs and Controllers
Jun 17, 2024

Introduction  In the ever-evolving landscape of web development, simplicity is key. Enter Minimal APIs in ASP.NET Core, a lightweight and streamlined approach to building web applications. In this detailed blog, we'll explore the concept of Minimal APIs, understand why they matter, and walk through their implementation in ASP.NET Core.    When to Use Minimal APIs?  Minimal APIs are well-suited for small to medium-sized projects, microservices, or scenarios where a lightweight and focused API is sufficient. They shine in cases where rapid development and minimal ceremony are top priorities.  You can find in this blog <link> how to create minimal api.  I am directly showing the comparison between MinimalAPI and controller.    Controllers: Structured and Versatile  Controllers, deeply rooted in the MVC pattern, have been a cornerstone of ASP.NET API development for years. They provide a structured way to organize endpoints, models, and business logic within dedicated controller classes.  Let's consider an example using Microsoft.AspNetCore.Mvc; namespace MinimalAPI.Controllers { [ApiController] [Route("[controller]")] public class WeatherForecastController : ControllerBase { private static readonly string[] Summaries = new[] { "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching" }; private readonly ILogger<WeatherForecastController> _logger; public WeatherForecastController(ILogger<WeatherForecastController> logger) { _logger = logger; } [HttpGet(Name = "GetWeatherForecast")] public IEnumerable<WeatherForecast> Get() { return Enumerable.Range(1, 5).Select(index => new WeatherForecast { Date = DateOnly.FromDateTime(DateTime.Now.AddDays(index)), TemperatureC = Random.Shared.Next(-20, 55), Summary = Summaries[Random.Shared.Next(Summaries.Length)] }) .ToArray(); } } } Advantages of Controllers in Action  Structure and Organization: Controllers offer a clear structure, separating concerns and enhancing maintainability.  Flexibility: They enable custom routes, complex request handling, and support various HTTP verbs.  Testing: Controllers facilitate unit testing of individual actions, promoting a test-driven approach   Minimal APIs: Concise and Swift  With the advent of .NET 6, Minimal APIs emerged as a lightweight alternative, aiming to minimize boilerplate code and simplify API creation.  Here's an example showcasing Minimal APIs.  using MinimalAPI; var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddControllers(); // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle builder.Services.AddEndpointsApiExplorer(); builder.Services.AddSwaggerGen(); var app = builder.Build(); app.MapGet("/GetWeatherForecast", () => { var rng = new Random(); var summaries = new[] { "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching" }; var weatherForecasts = Enumerable.Range(1, 5).Select(index => new WeatherForecast { Date = DateTime.Now.AddDays(index).Date, TemperatureC = rng.Next(-20, 55), Summary = summaries[rng.Next(summaries.Length)] }).ToArray(); return Results.Ok(weatherForecasts); }); // Configure the HTTP request pipeline. if (app.Environment.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); } app.UseHttpsRedirection(); app.UseAuthorization(); app.MapControllers(); app.Run(); Advantages of Minimal APIs in Focus  Simplicity: Minimal APIs drastically reduce code complexity, ideal for smaller projects or rapid prototyping.  Ease of Use: They enable quick API creation with fewer dependencies, accelerating development cycles.  Potential Performance Boost: The reduced overhead might lead to improved performance, especially in smaller applications.    What you choose between MinimalAPI and Controller?  Choosing between Controllers and Minimal APIs hinges on various factors.  Project Scale: Controllers offer better organization and structure for larger projects with intricate architectures.  Development Speed: Minimal APIs shine when speed is crucial, suitable for rapid prototyping or smaller projects.  Team Expertise: Consider your team's familiarity with MVC patterns versus readiness to adopt Minimal APIs.    Conclusion  The decision between Controllers and Minimal APIs for .NET APIs isn't about one being superior to the other. Rather, it's about aligning the choice with the project's specific needs and constraints. Controllers offer robustness and versatility, perfect for larger, complex projects. On the other hand, Minimal APIs prioritize simplicity and rapid development, ideal for smaller, more straightforward endeavours. 

Role based Authorization in ASP .NET core
Jun 14, 2024

What is Authorization?  Authorization verifies whether a user has permission to use specific applications or services. While authentication and authorization are distinct processes, authentication must precede authorization, ensuring the user's identity is confirmed before determining their access rights.    When logging into a system, a user must provide credentials like a username and password to authenticate. Next, the authorization process grants rights. For example, an administrative user can create a document library to add, edit, and delete documents, while a non-administrative user can only read documents in the library.  Types of Authorization:  Simple Authorization  Role-Based Authorization  Claim-Based Authorization  Policy-Based Authorization  I have implemented an example of role-based authorization in .NET. Step 1: Create one new MVC Web Application with the Authentication type “Individual Account”.  Step 2: Register Identity with DefaultTokenProvider in the program.cs file. builder.Services.AddIdentity<IdentityUser, IdentityRole>(options => options.SignIn.RequireConfirmedAccount = false) .AddEntityFrameworkStores<ApplicationDbContext>() .AddDefaultTokenProviders(); For better understanding, I have added one page to add a new role.  Create a new method in the controller and add the following code. [HttpGet] public IActionResult Admin() { return View(); } Create a new model Role.cs.   namespace Authorization.Models { public class Role { public string RoleName { get; set; } } } Create html page for add role.  @model Role @{ ViewData["Title"] = "Admin"; } <h1>Admin</h1> <div class="row"> <div class="col-md-12"> <form method="post" action="@Url.Action("Admin","Home")"> <div class="form-group"> <label>Role Name</label> <input type="text" class="form-control" style="width:30%;" asp-for="RoleName" placeholder="Role name" required> </div> <br /> <button class="btn btn-success" type="submit">Add</button> </form> </div> </div> I have created a simple page, You can modify the page as per your requirements.  Add a new method in the controller and add the following code. And declare RoleManager<IdentityRole> and inject in the constructor. private readonly RoleManager<IdentityRole> _roleManager; public HomeController(RoleManager<IdentityRole> roleManager) { _roleManager = roleManager; } [HttpPost] public async Task<IActionResult> Admin(Role role) { var result = _roleManager.RoleExistsAsync(role.RoleName).Result; if (!result) { await _roleManager.CreateAsync(new IdentityRole(role.RoleName)); } return RedirectToAction("Admin"); } Set a new tab in _Layout.cshtml file to redirect to the Add role page.  <li class="nav-item"> <a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Admin">Add new role</a> </li> Run the project and you will see the output. Here, You can add a new role.  Add a new field in register.cshtml using the following code to assign a role to the user.  <div class="form-floating mb-3"> <select asp-for="Input.Role" class="form-control" aria-required="true"> <option value="">Select role</option> @foreach (var item in Model.RoleList) { <option value="@item.Name">@item.Name</option> } </select> <span asp-validation-for="Input.ConfirmPassword" class="text-danger"></span> </div> To get the list of roles you can add the following code in your register.cshtml.cs file. And Add  RoleList = _roleManager.Roles in OnPostAsync method also. public IQueryable<IdentityRole> RoleList { get; set; } public async Task OnGetAsync(string returnUrl = null) { ReturnUrl = returnUrl; RoleList = _roleManager.Roles; ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList(); } Run the project and see the output. Now, Assign the role to the user, and for that add the following code in OnPostAsync after the user is created. await _userManager.AddToRoleAsync(user, Input.Role); Full code of register.cshtml.cs file. using Microsoft.AspNetCore.Authentication; using Microsoft.AspNetCore.Identity; using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Mvc.RazorPages; using Microsoft.AspNetCore.WebUtilities; using System.ComponentModel.DataAnnotations; using System.Text; namespace Authorization.Areas.Identity.Pages.Account { public class RegisterModel : PageModel { private readonly SignInManager<IdentityUser> _signInManager; private readonly UserManager<IdentityUser> _userManager; private readonly RoleManager<IdentityRole> _roleManager; private readonly IUserStore<IdentityUser> _userStore; private readonly IUserEmailStore<IdentityUser> _emailStore; private readonly ILogger<RegisterModel> _logger; //private readonly IEmailSender _emailSender; public RegisterModel( UserManager<IdentityUser> userManager, IUserStore<IdentityUser> userStore, SignInManager<IdentityUser> signInManager, ILogger<RegisterModel> logger, RoleManager<IdentityRole> roleManager ) { _userManager = userManager; _userStore = userStore; _emailStore = GetEmailStore(); _signInManager = signInManager; _roleManager = roleManager; _logger = logger; } [BindProperty] public InputModel Input { get; set; } public IQueryable<IdentityRole> RoleList { get; set; } public string ReturnUrl { get; set; } public IList<AuthenticationScheme> ExternalLogins { get; set; } public class InputModel { [Required] [EmailAddress] [Display(Name = "Email")] public string Email { get; set; } [Required] [Display(Name = "Role")] public string Role { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } } public async Task OnGetAsync(string returnUrl = null) { ReturnUrl = returnUrl; RoleList = _roleManager.Roles; ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList(); } public async Task<IActionResult> OnPostAsync(string returnUrl = null) { returnUrl ??= Url.Content("~/"); RoleList = _roleManager.Roles; ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList(); if (ModelState.IsValid) { var user = CreateUser(); await _userStore.SetUserNameAsync(user, Input.Email, CancellationToken.None); await _emailStore.SetEmailAsync(user, Input.Email, CancellationToken.None); var result = await _userManager.CreateAsync(user, Input.Password); if (result.Succeeded) { _logger.LogInformation("User created a new account with password."); await _userManager.AddToRoleAsync(user, Input.Role); var userId = await _userManager.GetUserIdAsync(user); var code = await _userManager.GenerateEmailConfirmationTokenAsync(user); code = WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(code)); if (_userManager.Options.SignIn.RequireConfirmedAccount) { return RedirectToPage("RegisterConfirmation", new { email = Input.Email, returnUrl = returnUrl }); } else { await _signInManager.SignInAsync(user, isPersistent: false); return LocalRedirect(returnUrl); } } foreach (var error in result.Errors) { ModelState.AddModelError(string.Empty, error.Description); } } return Page(); } private IdentityUser CreateUser() { try { return Activator.CreateInstance<IdentityUser>(); } catch { throw new InvalidOperationException($"Can't create an instance of '{nameof(IdentityUser)}'. " + $"Ensure that '{nameof(IdentityUser)}' is not an abstract class and has a parameterless constructor, or alternatively " + $"override the register page in /Areas/Identity/Pages/Account/Register.cshtml"); } } private IUserEmailStore<IdentityUser> GetEmailStore() { if (!_userManager.SupportsUserEmail) { throw new NotSupportedException("The default UI requires a user store with email support."); } return (IUserEmailStore<IdentityUser>)_userStore; } } } Now, register one new user and assign a role to them. For example, I have created one user and assign “Admin” to them. I have added two new methods in the controller and added a default view for that.  [Authorize(Roles = "User")] public IActionResult UserRoleCheck() { return View(); } [Authorize(Roles = "Admin")] public IActionResult AdminRoleCheck() { return View(); } I have set the Authorize attribute with the role name on both authorization methods. Now, I am running the project and clicking on Admin Role, It will open the page of admin because the logged user role and method role both are the same.  If I click on User Role, It will give an Access denied error. Because logged user role and method role both are different. Here, I am using by default access denied page of identity. You can use custom page also, Just set this path to program.cs file. builder.Services.ConfigureApplicationCookie(options => { options.AccessDeniedPath = "/Identity/Account/AccessDenied"; // Customize this path as per your application's structure }); Using this way you will implement the role-based authorization in your application. Conclusion  By properly implementing authorization in your applications, you can ensure that resources and sensitive information are accessible only to authorized users. Remember to choose the appropriate authorization technique based on your application’s requirements and complexity.

Enhancing Performance and Manageability: Table Partitioning in Microsoft SQL Server
Jun 14, 2024

Introduction Overseeing data management and performance optimization, implementing table partitioning in Microsoft SQL Server is a strategic decision to enhance database performance and manageability. Table partitioning is a powerful technique that allows large tables to be divided into smaller, more manageable pieces, improving query performance and simplifying maintenance tasks. In this blog, we'll explore the concept of table partitioning, its benefits, and a step-by-step guide to implementing it in SQL Server.   Understanding Table Partitioning Table partitioning involves dividing a large table into smaller, more manageable segments called partitions. Each partition can be managed and accessed independently, which can significantly improve query performance and simplify maintenance tasks. Partitioning is especially beneficial for large tables with millions or billions of rows, where operations such as data loading, archiving, and querying can become cumbersome.   Key Concepts Partition Function: Defines how data is distributed across partitions based on a specified column or columns. Partition Scheme: Maps the partitions defined by the partition function to specific filegroups within the database. Aligned Indexes: Indexes that are partitioned in the same way as the table, ensuring that queries using these indexes benefit from partitioning.   Benefits of Table Partitioning Improved Query Performance: Queries that target specific partitions can avoid scanning the entire table, resulting in faster response times. Parallel processing of partitions can enhance performance for complex queries. Simplified Maintenance: Partition-level operations such as loading, archiving, and deleting data can be performed independently, reducing the impact on overall database performance. Easier management of large tables, as partitions can be individually managed and optimized. Enhanced Data Management: Partitioning can facilitate better data organization and management, such as separating historical data from current data. Efficient handling of data purging and archiving processes. Types of Table Partitions in SQL Server 1. Range Partitioning Range partitioning is the most common type of partitioning in SQL Server. It involves dividing a table based on a range of values in a specified column, often a date or numerical column. Each partition holds data that falls within a specific range. Use Cases: Partitioning data by date to manage historical data efficiently. Improving query performance for range-based queries. Example: CREATE PARTITION FUNCTION rangePartitionFunction (datetime) AS RANGE LEFT FOR VALUES ('2021-01-01', '2022-01-01', '2023-01-01'); CREATE PARTITION SCHEME rangePartitionScheme AS PARTITION rangePartitionFunction TO (fg1, fg2, fg3, fg4); CREATE TABLE SalesData ( SaleID int, SaleDate datetime, Amount money ) ON rangePartitionScheme (SaleDate);   2. List Partitioning List partitioning allows you to divide a table based on a list of values. Each partition is associated with specific values of a column, often used for categorizing data by discrete values such as regions or departments. Use Cases: Partitioning data by specific categories (e.g., regions, product types). Enhancing query performance for category-based queries. Example: CREATE PARTITION FUNCTION listPartitionFunction (nvarchar(20)) AS RANGE LEFT FOR VALUES ('North', 'South', 'East', 'West'); CREATE PARTITION SCHEME listPartitionScheme AS PARTITION listPartitionFunction TO (fg1, fg2, fg3, fg4); CREATE TABLE SalesRegionData ( SaleID int, Region nvarchar(20), Amount money ) ON listPartitionScheme (Region);   3. Composite Partitioning Composite partitioning combines two or more partitioning strategies. The most common combination is range-list or range-hash partitioning. This approach allows for more complex and flexible data distribution strategies. Use Cases: Managing large datasets with multiple logical divisions. Enhancing performance and manageability for complex queries. Example: -- Range-List Partitioning Example CREATE PARTITION FUNCTION rangePartitionFunction (datetime) AS RANGE LEFT FOR VALUES ('2021-01-01', '2022-01-01', '2023-01-01'); CREATE PARTITION FUNCTION listPartitionFunction (nvarchar(20)) AS RANGE LEFT FOR VALUES ('North', 'South', 'East', 'West'); Choosing the Right Partitioning Strategy Selecting the appropriate partitioning strategy depends on several factors, including data characteristics, query patterns, and maintenance requirements. Here are some guidelines to help you choose: Range Partitioning: Best for time-series data or data with natural ranges. Ideal for scenarios where you frequently query specific ranges of data. List Partitioning: Suitable for categorical data with a limited number of discrete values. Useful for scenarios where queries target specific categories. Composite Partitioning: Best for complex data structures that require multiple partitioning dimensions. Ideal for large datasets with varied query patterns and maintenance needs. Implementing Table Partitioning in SQL Server Step 1: Planning and Design Identify Candidate Tables: Analyze your database to identify large tables that will benefit from partitioning. Consider factors such as table size, query patterns, and data lifecycle. Choose Partitioning Column: Select a column that will be used to distribute data across partitions, often based on date or range values. Ensure the column has a high degree of cardinality to evenly distribute data. Step 2: Creating a Partition Function Define the Partition Function: Create a partition function that specifies the boundaries for each partition. CREATE PARTITION FUNCTION myPartitionFunction (int) AS RANGE LEFT FOR VALUES (1000, 2000, 3000);   Step 3: Creating a Partition Scheme Map Partitions to Filegroups: Create a partition scheme that maps each partition to a specific filegroup. CREATE PARTITION SCHEME myPartitionScheme AS PARTITION myPartitionFunction TO (fg1, fg2, fg3, fg4);   Step 4: Creating a Partitioned Table Create the Table Using Partition Scheme: Create the partitioned table and specify the partition scheme. CREATE TABLE myPartitionedTable ( id int, data nvarchar(100), partition_column int ) ON myPartitionScheme (partition_column);   Step 5: Managing Indexes on Partitioned Tables Create Aligned Indexes: Ensure indexes are partitioned in the same way as the table. CREATE INDEX idx_myPartitionedTable ON myPartitionedTable (partition_column) ON myPartitionScheme (partition_column);   Step 6: Maintaining Partitioned Tables Data Management: Use partition-level operations for data loading, archiving, and purging. Utilize partition switching to efficiently move data between tables. Monitoring and Optimization: Regularly monitor partition performance and manage storage distribution. Rebuild or reorganize partitions as needed to maintain optimal performance. Conclusion Implementing table partitioning in Microsoft SQL Server is a powerful strategy for improving database performance and manageability, especially for large tables. Guiding your team through the careful planning and implementation of partitioning can lead to significant performance gains and simplified maintenance processes. By following the steps outlined in this blog, you can ensure a successful partitioning implementation that enhances your organization's data management capabilities. Table partitioning is not just a technical enhancement; it's a strategic move towards better data management and performance optimization. Embrace this powerful feature to keep your SQL Server environment robust and responsive.

Dependency Injection with Example
Jun 12, 2024

What is the Dependency Injection Design Pattern? Dependency Injection is a design pattern used to execute Inversion of control (IoC). It is a process of injecting the dependency object into a class that depends on it. Dependency Injection is the often-used design pattern these days to separate the dependencies between the objects that allow us to implement loosely coupled software components. It allows the making of dependent objects outside of the class and supplies those objects to a class in distinct ways. Let’s talk about the bit-by-bit process to implement dependency Injection in the ASP.Net Core application. The ASP.NET Core Framework provides inbuilt support for Dependency Injection design patterns. It injects the dependency objects to a class via a constructor, method, or property using the built-in IoC container. The inbuilt IoC container is elected by IServiceProvider implementation, which supports default construction injection. The classes managed by built-in IoC Containers are called services.   Types of Services in ASP.NET Core There are 2 types of services in ASP.NET core. Framework Services: Services that are a part of the ASP.NET core framework, like IApplicationBuilder, IHostingEnvironment, ILoggerFactory, etc. Application Services: The services you create as a programmer for your application. Before registering services, let’s first know the different methods to register a service. The ASP.NET core gives 3 methods to register a service with a Dependency Injection container. The method that we use to register a service will determine the lifetime of the service. Singleton: A Singleton service is created only once per application lifetime. The same instance is used all over the application. Common uses contain configuration services, logging, or other services where a single instance is enough and advisable. Since the same instance is used throughout, you need to ensure that Singleton services are thread-safe. Not suitable for saving user-specific data or request-specific data. This can be reached by adding the service as a singleton through the AddSingleton method of the IServiceCollection. Transient: A Transient service is created every time it is requested from the service container. This means that a new instance is provided to every class or method that requires it. Suitable for lightweight, stateless services. Since a new instance is created every time, you don’t need to worry about thread safety related to the internal state. While transient services are simple and provide clean separation, they can be more resource-intensive if they are vast or require significant resources to build. This can be got by adding the service through the AddTransient method of the IServiceCollection. Scoped: A scoped service is created once per client request (means per HTTP request). Perfect for services that need to maintain state within a single request but should not be shared across different requests. This can be achieved by adding the service through the AddScoped method of the IServiceCollection.   How to Register a Service with ASP.NET Core Dependency Injection Container? We need to register a service to the in-built dependency injection container with the program class.  The below code shows how to register a service with different lifetimes. var builder = WebApplication.CreateBuilder(args); // ADD FRAMEWORK MVC SERVICES TO THE CONTAINER builder.Services.AddMvc(); // ADD APPLICATION SERVICES TO THE CONTAINER builder.Services.Add(new ServiceDescriptor(typeof(ISubjectTypesDA), new SubjectTypesDA())); // BY DEFAULT SINGLETON builder.Services.Add(new ServiceDescriptor(typeof(ISubjectTypesDA), new SubjectTypesDA(),ServiceLifetime.Singleton)); // SINGLETON builder.Services.Add(new ServiceDescriptor(typeof(ISubjectTypesDA), new SubjectTypesDA(),ServiceLifetime.Transient)); // TRANSIENT builder.Services.Add(new ServiceDescriptor(typeof(ISubjectTypesDA), new SubjectTypesDA(),ServiceLifetime.Scoped)); // SCOPED   What is the ServiceDescriptor class in .NET Core? This class speaks for a descriptor of a service in the DI Container. It essentially describes how to service should be instantiated and managed by the container. So, it describes a service, including its lifetime, the service type, and the implementation type. Extension methods for Registration ASP.NET Core framework contains extension methods for each type of lifetime: AddSingleton, AddTransient, and AddScoped methods.  The below example shows how to register types of lifetimes using extension methods. // ADD APPLICATION SERVICE TO THE CONTAINER. services.AddTransient<IEmailSenderBL, EmailSenderBL>(); // TRANSIENT services.AddScoped<ISubjectTypesBL, SubjectTypesBL>(); // SCOPED services.AddSingleton<ICPCalculationBL, CPCalculationBL>(); // SINGLETON   The dependent class is a class which depends on the dependency class. The dependency class is a class that provides service to the dependent class. The interface injects the dependency class object into the dependent class.   There are 3 types of Dependency Injection. Constructor Injection Property Injection Method Injection   Constructor Injection: we register the service, the IoC automatically executes constructor injection if a service type is included as a parameter in a constructor. Example: public class CenterController : BaseController { private ICenterBL _centerBL; public CenterController(ICenterBL centerBL) : base(myLoginUser) { _centerBL = centerBL; } [Authorize] public IActionResult Index() { try { var data = _centerBL.GetCenterpageList(); return View(data); } catch (Exception EX) { throw EX; } } }   Property Injection: Not required to add dependency services in the constructor. We can manually access the services configured with built-in IoC containers using the RequestServices property of HttpContext.   public class AddressController : Controller { [Authorize] public IActionResult Index() { var services = this.HttpContext.RequestServices; IAddressBL _address = (IAddressBL)services.GetService(typeof(IAddressBL)); var data = _address.GetAddressList(); return View(data); } }   Method Injection: Occasionally, we may only need a dependency object in a single action method. In that case, we need to use the [FromServices] attribute with the service type parameter in the action method. In the below example, you can see we are using the [FromServices] attribute within the Index action method. So, at runtime, the IoC Container will inject the dependency object to the IAddressBL repository reference variable. As we inject the dependency object through a method, it is called method dependency injection. public class CommonController: Controller { public IActionResult Index([FromServices] IAddressBL _addressBL) { var list = _addressBL.GetAddressList(); return View(list); } } Advantages of Dependency Injection Loose Coupling: we can separate our classes from their dependencies. This results in code that is simpler to maintain and test. Testability: we can increase the testability of our code since we can easily replace dependencies with mock objects during unit testing. Extensibility: enhance the extensibility of our code by offering the flexibility to switch out dependencies conveniently. Reusability: makes our code more reusable since we can conveniently share dependencies among various classes.
