 Complete Tutorial on Developing Custom Middleware in ASP.NET Core MVC: Middleware plays a crucial role in handling requests and responses in an ASP.NET Core application. This comprehensive tutorial will guide you through the process of creating custom middleware in an ASP.NET Core MVC application, using a practical example to demonstrate key concepts. 1. Introduction Middleware in ASP.NET Core is a software component that is executed on each request. It can be used to handle various concerns like authentication, logging, error handling, and more. Middleware components form a pipeline, and each component can process requests, generate responses, and call the next middleware in the sequence. 2. Setting Up the Project Create a New ASP.NET Core MVC Project: Open Visual Studio and create a new project. Select "ASP.NET Core Web Application" and click "Next". Name your project (e.g., "CustomMiddlewareExample"), select "ASP.N...

  Understanding Dependency Injection (DI) in ASP.NET Core Introduction Dependency Injection (DI) is a design pattern that helps achieve Inversion of Control (IoC) between classes and their dependencies. ASP.NET Core provides built-in support for DI, making it easier to manage dependencies and create loosely coupled, testable, and maintainable code. What is Dependency Injection? Dependency Injection is a technique where an object receives its dependencies from an external source rather than creating them internally. This promotes loose coupling and makes the code more modular and easier to test. Why Use Dependency Injection in ASP.NET Core? Loose Coupling : DI helps in reducing dependencies between classes, making the code more modular and easier to maintain. Testability : DI makes it easier to mock dependencies during unit testing, leading to more reliable tests. Reusability : DI promotes the reuse of components, as dependencies can be eas...
