FIX: An incorrect instance size is generated when you use the Type Library Exporter to generate a type library from a CLR assembly in the .NET Framework 2.0 Service Pack 2

SYMPTOMS
In the Microsoft .NET Framework 2.0 Service Pack 2 (SP2), when you use the Type Library Exporter (Tlbexp.exe) to generate a type library from a common language runtime (CLR) assembly, an incorrect instance size is generated. This problem occurs if the following conditions are true:
  • One type in the project refers to a second type in the project.
  • The second type occurs after the first type.
CAUSE
This problem occurs because the Layout method or another method that leads to the Layout method is called before a type and its dependencies are created completely. For example, the ITypeInfo::GetTypeAttr method is called before a type and its dependencies are created completely.
