ApiPort reports TypeInfo.IsClass is not supported in .NET 4.5

[danielturcanu]

Wrote some small test code
TypeInfo info = IntrospectionExtensions.GetTypeInfo(GetType());
IsClass = info.IsClass;

For this ApiPort reports that TypeInfo.IsClass is not supported in .NET 4.5, but supported in .NET Core.
I can run this code just fine in .NET 4.5 though.

Thanks @danielturcanu. We know there are some issues around Type/TypeInfo (see #113) and the way we can analyze them via IL. This may be related, but I'll take a look.

Yes, this is related. We think we have a workaround, but we'll track that in the original issue
