COM Signature

From vsshell80.idl:

HRESULT IVsAggregatableProject::GetAggregateProjectTypeGuids(
   [out] BSTR *pbstrProjTypeGuids

The Project type GUIDs are a semi-colon delimited list of project factory GUIDs in order of aggregation from outer-most project subtype to the inner-most project subtype. This list also includes the GUID of the inner (base) project. This list is managed by the inner-most project and is persisted in its project file.


It is not necessary for the GUID of the base project itself to be persisted in the project file. The inner-most base project may also choose to strip its own GUID before persisting and implicitly adding it when retrieving the list of GUIDs.
