How can I implement error handling in my MVC application?

You can implement error handling in your MVC application by using custom error pages, exception filters, and logging.

What are exception filters and how do I use them?

Exception filters allow you to handle exceptions globally or at the controller level. You can create a custom filter by inheriting from the IExceptionFilter interface.

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

Sure! Here's a simple example:

public class CustomExceptionFilter : IExceptionFilter
{
    public void OnException(ExceptionContext context)
    {
        // Log the exception
        // Return a custom error view
        context.Result = new ViewResult { ViewName = "Error" };
        context.ExceptionHandled = true;
    }
}

How do I log errors in my application?

You can log errors using built-in logging frameworks like Serilog or NLog. Just configure the logger in your Startup.cs and use it in your controllers.
