When you implement a plug-in data source using C++ or any other COM-compliant language that supports aggregation, your PlugInWorkspaceFactoryHelper coclass must aggregate the PlugInWorkspaceFactory coclass.
When you implement a plug-in data source using a language that does not support aggregation (such as C# or other .NET languages), your PlugInWorkspaceFactoryHelper coclass does not aggregate the PlugInWorkspaceFactory coclass. Instead, the PlugInWorkspaceFactory coclass will aggregate your PlugInWorkspaceFactoryHelper coclass.
