// it doesn't have to do that because it can directly create a typeref with the class interface name,
// without actually creating anything like the TypeBuilder. The result is that the name would be different
// with interop assemblies generated by old tlbimp in this case.
// Given the nature of reflection API, this cannot be easily workarounded unless we switch to metadata APIs.
// I believe this is acceptable because this only happens when:
// 1. People decide to migrate newer .NET framework
