Custom Exception Filter not being hit in asp.net MVC - asp.net-mvc

Question

I have a custom exception filter that I'm using to catch a custom exception that I wrote but for some reason when I throw my exception, it's not ever getting to the filter. Instead I just get an error that my exception was not handled by user code. Can anyone please provide some advice/assistance as to how I should have this set up? Relevant code is below:
// controller
[CustomExceptionFilter]
public class SomeController : Controller
{
public SomeController()
{
}
public ActionResult Index()
{
SomeClass.SomeStaticMethod();
return View();
}
}
that's the controller with the customexception attribute
// some class (where exception is being thrown)
public class SomeClass
{
public static void SomeStaticMethod()
{
throw new MyCustomException("Test");
}
}
that's the class (for my test) that throws the exception (I've also tried throwing it directly on the controller).
// Custom exception filter (want this to catch all unhandled exceptions)
public class CustomExceptionFilter : FilterAttribute, IExceptionFilter
{
public void OnException(ExceptionContext filterContext)
{
if (filterContext.Exception.GetType() == typeof(MyCustomException))
{
// do stuff
}
}
}
that's the custom exception filter...it's never being reached when the code is executed and the exception is thrown. Instead I get the error mentioned above. Everything I've read indicates that this is the proper way to set this up, but when I put breakpoints in my custom filter, it's never being hit....
What am I missing here?
TIA

Once you've handled your error, you need to let the filter context know it has been handled. Like this:
filterContext.ExceptionHandled = true;
This should be in your '// do stuff' section.
I've copied your code, and the filter is getting called fine. The only difference I made was I added the exceptionHandled code and adding my breakpoint at that line.
