Symptom 1When you use the Regasm.exe utility to generate and to register a type library, you may receive the following error message:
Symptom 2When you use the TlbExp.exe utility to generate a type library, you may receive the following error message:
Symptom 3A Visual Studio 2008 package implements a property collection that is exposed by the EnvDTE.DTE.Properties property. If the collection is a member of an object that uses a type from the Microsoft.VisualStudio.Shell.Interop.dll assembly, the common language runtime (CLR) will not construct the necessary in-memory type library for the assembly. For example, the following Visual Studio macro that references the EnvDTE.DTE.Properties property will fail, and then you will receive an error message.
Dim proj As Project = DTE.Solution.Projects.Item(1)
Dim props As Properties = proj.ConfigurationManager.ActiveConfiguration.Properties
Because the ImportedFromTypelib attribute was removed in Visual Studio 2008, the CLR cannot construct the necessary in-memory type library for the Microsoft.VisualStudio.Shell.Interop.dll assembly. This failure is caused by duplicate type GUIDs.
