// We have to create class interface ahead of time because of the need to convert default interfaces to

// before the other interfaces, because we need to create the type builder for the event interface first
// so that we can create a class interface that implement it. But in the previous version of TlbImp,
// 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
// 2. The event interface name conflicts with a normal interface
//
// In this case the problem can be easily fixed with a global refactoring, so I wouldn't worry about that
