Where should a project system implement IVsGetCfgProvider

Hello,

Based on the BscPrj sample and the MPF project sample, a project system implements IVsCfgProvider on the same object that implements IVsHierarchy.

Should a project system always implement IVsGetCfgProvider on the same object as IVsHierarchy This seems to be the case in the sample code but doesn't seem to happen in C# nor VB .NET projects. I'm listening for OnAfterOpenProject in my package, which passes in IVsHierarchy reference. In the case of the sample projects, I can do a QI to get the IVsGetCfgProvider interface. This doesn't work for C# nor VB .NET projects.

Thanks,
Notre

Thanks to a MS email, the answer is the following:

We give several options to where a project implements IVsCfgProvider[1,2] and IVsProjectCfgProvider. The options are:< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
1. We first try to get the VSHPROPID_BrowseObject for the VSITEMID_ROOT (via IVsHierarchy::GetProperty) and see if it implements IVsGetCfgProvider or IVsCfgProvider
2. Next we try to QI for IVsGetCfgProvider
3. Next we try to QI directly for IVsCfgProvider
