DotNet Core Api

Dotnet Core API refers to the ASP.NET Core framework, which is a cross-platform, high-performance framework for building web applications and APIs using the .NET platform. It allows developers to build scalable, robust, and efficient APIs that can be used to expose data and functionality to clients.

Here are some key features and concepts related to building a .NET Core API:

1. Routing: ASP.NET Core provides a flexible routing system that allows you to define URL patterns and map them to appropriate controller actions.

2. Controllers: Controllers in ASP.NET Core handle incoming HTTP requests and return responses. They contain action methods that are responsible for processing requests and producing responses.

3. Models: Models represent the data structures used by your API. They can be simple classes or more complex objects that define the structure of incoming request payloads or outgoing response bodies.

4. Middleware: Middleware components are used to handle requests and responses in the ASP.NET Core pipeline. They can perform various tasks like authentication, authorization, logging, exception handling, etc.

5. Dependency Injection: ASP.NET Core has built-in support for dependency injection, which helps in managing the dependencies of your application and promotes modular and testable code.

6. Content Negotiation: ASP.NET Core allows you to handle different data formats (e.g., JSON, XML) by performing content negotiation. Clients can request data in a specific format, and the API can respond accordingly.

7. Authentication and Authorization: ASP.NET Core provides a flexible authentication and authorization system that allows you to secure your API endpoints. You can use various authentication schemes, such as JWT, OAuth, etc., to authenticate and authorize users.

8. Testing: ASP.NET Core APIs can be easily tested using unit tests and integration tests. The framework provides testability features and supports popular testing frameworks like xUnit, NUnit, and MSTest.

To create a .NET Core API, you can use Visual Studio or any text editor along with the .NET Core SDK. You define your routes, controllers, models, and other necessary components to implement the desired functionality. Once developed, you can host your API on various platforms, including IIS, Azure, Docker containers, etc.
