InvalidOperationException with two Parameters of the same Type

[mjeanrichard]

The following Code results in an InvalidOperationException. If I remove one parameter from the Message or change the type of one of the parameters everything works fine. The Error only happens when I configure a custom TraceParameter (see example).

using System;
using System.Diagnostics.Tracing;
using EventSourceProxy;

namespace ConsoleApplication2
{
    [EventSourceImplementation(Name = "Test", ImplementComplementMethods = false)]
    public interface ITestEvents
    {
        [Event(100, Message = "Test {0}, {1}.", Level = EventLevel.Verbose)]
        void MyLog(Type t, Type t2);
    }

    class Program
    {
        static void Main(string[] args)
        {
            TraceParameterProvider.Default.ForAnything().With<Type>().Trace(t => t.FullName);
            EventSourceImplementer.GetEventSourceAs<ITestEvents>().MyLog(typeof(string), typeof(int));
        }
    }
}

Looks like the issue is that a function applied to a type, and the type is used twice in the parameter list, and the processing is treating them as the same parameter.

Should be fixed in 4.0.0
