I have a ASP WebAPI project. I'm trying to setup a global exception handler on my basecontroller. So I created an ExceptionFilterAttribute like so.

using System.Web.Http.Filters;

public class MyExceptionFilterAttribute : ExceptionFilterAttribute
{
    protected static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

    public override void OnException(HttpActionExecutedContext actionExecutedContext)
    {
        var exception = actionExecutedContext.Exception;
        log.Fatal(exception);

        base.OnException(actionExecutedContext);
    }
}

Then I also registered it in /App_Start/WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // ...

        // Setup Filters
        config.Filters.Add(new MyExceptionFilterAttribute());
    }
}

When I add the attributes to my controller (or base-controller), nothing gets logged. What am I doing wrong?

Edit: My controller throwing the exception:

[HttpGet]
public string Hello(string name)
{
    if (name.Equals("error", StringComparison.OrdinalIgnoreCase))
    {
        throw new HttpResponseException(HttpStatusCode.InternalServerError);
    }
    else
    {
        return name;
    }
}
