What are Middleware and filters

Question

Accepted Answer

Middleware and filters are components in ASP.NET Core that allow you to handle requests and responses in the pipeline.

Middleware are components that are added to the request pipeline to handle requests and responses.
Filters are used to implement cross-cutting concerns like logging, exception handling, and authorization.
Middleware can be used to modify the request or response before it reaches the controller action.
Filters can be applied globally, at the controller level, or at the action level.
Example of middleware: Authentication middleware that checks if the request is authenticated before reaching the controller.
Example of filter: Authorization filter that checks if the user has the necessary permissions to access a specific action.
