GetArguments() doesn't return anything for AttributeUsageAttribute

[asklar]

I have an attribute and I want to reflect over its AttributeUsage attribute
However when I get the AttributeUsageAttribute instance, doing GetArguments(,) returns no fixed nor named args.

I think the fix is to add a FakeType resolver for System.Runtime to mscorlib:

            loadContext.FakeTypeRequired += (sender, e) =>
            {
                var ctx = sender as MrLoadContext;
                if (e.AssemblyName == "Windows.Foundation.FoundationContract" || e.AssemblyName == "Windows.Foundation.UniversalApiContract")
                {
                    e.ReplacementType = ctx.GetTypeFromAssembly(e.TypeName, "Windows");
                }
                else if (e.AssemblyName == "System.Runtime")
                {
                    e.ReplacementType = ctx.GetTypeFromAssembly(e.TypeName, "mscorlib");
                }
            };

Do you have an example winmd/assembly? System.Runtime in .Net Framework is confusing because it's split across two DLLs (System.Runtime and mscorlib).
