Interfaces not defined on the IVsProject object

Comparing to the current VB/C# projects, you may find some interfaces are missing on CPS's implementation of the IVsProject object. Starting in VS 2017 CPS now supports a limited form of COM aggregation.

These interfaces are not implemented currently.

• IVsSingleFileGeneratorFactory
• IVsProjectResources
• IVsDeferredSaveProject
• IVsAsynchOpenFromSccProjectEvents
• IVsProjectBuildMessageReporter

The two interfaces below are not implemented by design. CPS is designed to be extended via MEF instead of COM aggregation. They can however be defined by extenders using COM aggregation.

• IVsAggregatableProject
• IVsProjectFlavorCfgProvider
