MVC 4 Global Exception Filter how to implement?

Question

How do I implement a global exception handler in MVC4 as it seems to be different from MVC3.

Not sure how to implement the following:

public class E         


        

Answer 1

The way I created an exception handler for MVC part of it, I created a class that implemented IExceptionFilter

public class MVCExceptionFilter : IExceptionFilter
{
    public void OnException(ExceptionContext filterContext)
    {
        Trace.TraceError(filterContext.Exception.ToString());
    }
}

You then register it in the Global.asax.cs inside protected void Application_Start()

The method already contains the line

FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

So, you will need to add this line ABOVE it

GlobalFilters.Filters.Add(new MVCExceptionFilter());
