Question

Aryan Kumar · Answer

Startup.cs is a file in a .NET Core API project that is used to configure the application. It is typically located in the root directory of the project.
The Startup.cs file contains the following sections:
Configuration: This section is used to configure the application's dependencies, such as the database and the logging framework.Services: This section is used to register the application's services, such as the controllers and the middleware.Middleware: This section is used to configure the application's middleware, which is used to handle HTTP requests and responses.Endpoints: This section is used to define the application's endpoints, which are the URLs that can be used to access the application.
The Startup.cs file is a critical part of a .NET Core API project. It is used to configure the application and define its endpoints.
Here are some additional tips for writing a Startup.cs file:
Use dependency injection to inject dependencies into your services. This will help to make your code more modular and easier to test.Use middleware to handle common tasks, such as authentication and authorization. This will help to keep your code clean and organized.Use endpoints to define the URLs that can be used to access your application. This will help to make your application more discoverable and easier to use.
