Question

I want to handle uncaught exceptions in my ASP.NET MVC 3 application, so that I may communicate the error to the user via the application\'s error view. How do I intercept u

you can use HandleErrorAttribute filters,

[ErrorHandler(ExceptionType = typeof(Exception), View = "UnhandledError", Order = 1)]
 public abstract class BaseController : Controller

        {
    }

basically you can have this on top of a base controller and define the UnhandledError.cshtml in the Shared views folder.

And if you want to log the unhandled errors before you show the error message then you can extend the HandleErrorAttribute class and put the logic to do the logging inside the OnException method.

public class MyErrorHandlerAttribute : HandleErrorAttribute
    {


        public override void OnException(ExceptionContext exceptionContext)
        {
            Logger.Error(exceptionContext.Exception.Message,exceptionContext.Exception);
            base.OnException(exceptionContext);
        }
    }
