	uint grfAddVPFlags,
	ref Guid rguidProjectID
)

Parameters

[in] Pointer to a hierarchy object.

grfAddVPFlags

COM Signature

From vsshell.idl:

HRESULT IVsSolution::AddVirtualProjectEx(
   [in] IVsHierarchy *pHierarchy,
   [in] VSADDVPFLAGS grfAddVPFlags,
   [in] REFGUID rguidProjectID
);

This method is the same as AddVirtualProject except that the caller can specify a per-instance GUID project identifier (rGUIDProjectID) for this project to enable GetProjectOfGuid and GetProjectOfProjref to function properly. The caller is responsible for persisting this instance GUID and passing the same GUID when reloading the same project instance.

NoteNote:

The GUID project identifier is not the same as the GUID project type. CoCreateGuid() is useful for creating new GUIDs.
