IVsAggregatableProject Interface
Implemented by a project that supports adding project subtypes through aggregation.
Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop.8.0 (in microsoft.visualstudio.shell.interop.8.0.dll)

A project subtype must be implemented by a valid VSPackage that implements the IVsPackage interface and provides a project factory that supports the IVsAggregatableProjectFactory and IVsAggregatableProject interfaces. A project subtype is registered in the system registry similar to a normal project. Project subtype adds a unique GUID under the following location in the registry:
HKLM\Software\Microsoft\VisualStudio\[targeted version of VSIP]\Projects
Notes to Implementers Implement the IVsAggregatableProject interface when your project supports project subtypes through aggregation. Each level in project aggregation has to implement this interface as well as have a project factory that implements the IVsAggregatableProjectFactory interface.
