This returns true in three scenarios:

  1. A managed interface corresponding to a COM interface - The managed interface is marked with ComImportAttribute and a GuidAttribute with the UUID of the COM interface
  2. A managed interface corresponding to a COM coclass - When the Type Library Importer (tlbimp.exe) imports a COM coclass (say "Foo"), it creates a managed interface with the same name (ie. "Foo), and a managed class with the string "Class" appended (ie. "FooClass"). The managed interface is marked with ComImportAttribute, a Guid attribute with the CLSID of the COM coclass, and a CoClassAttribute pointing to the managed class. The managed class inherits from the managed interface, and has a Guid attribute with the CLSID of the COM coclass.
  3. A managed class inheriting from a managed interface marked with ComImportAttribute - This is "FooClass" above.
