What are the best practices for error handling in ASP.NET Core?

In ASP.NET Core, best practices for error handling include using middleware for centralized error handling, logging errors, and returning appropriate HTTP status codes.

Can you explain how to implement middleware for error handling?

Sure! You can create a custom middleware by implementing the IMiddleware interface or using a simple class with a Invoke method. In this method, you can catch exceptions and handle them accordingly.

What about logging errors? How should I do that?

You can use built-in logging providers like Serilog or NLog. Configure them in Startup.cs and log errors in your middleware or exception handling logic.

How do I return custom error responses?

You can return custom error responses by creating a custom response object and serializing it to JSON in your middleware when an exception occurs.
