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

In ASP.NET Core, best practices for exception handling include using middleware for centralized error handling, logging exceptions, 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, catch exceptions and log them, then return a user-friendly error response.

What should I log when an exception occurs?

You should log the exception message, stack trace, and any relevant context information, such as user ID or request details, to help diagnose the issue.

How can I return custom error responses?

You can return custom error responses by creating a response object and serializing it to JSON. Set the response status code and content type accordingly.
