How can I implement custom exceptions in ASP.NET MVC?

You can create a custom exception class by inheriting from the built-in Exception class. Then, you can throw this exception in your controllers.

Can you show me an example of a custom exception class?

Sure! Here's a simple example:

public class CustomNotFoundException : Exception
{
    public CustomNotFoundException(string message) : base(message) {}
}

How do I handle this custom exception in my controller?

You can use a try-catch block in your controller action to catch the custom exception and return an appropriate response.

What if I want to log the exception details?

You can log the exception details in the catch block using a logging framework like NLog or Serilog.
