SharedMSBuildFilesManagerHierarchy Interface
A project hierarchy with shared MSBuild files. In the Save Changes dialog, this project file appears with the name "[Shared MSBuild Project Files]". This node appears in the Save Changes dialog when there are shared MSBuild files that need to be saved and the files do not have affinity to a particular shared assets project. A new singleton instance of this hierarchy is created (if necessary) for each solution and closed when the solution closes. This singleton hierarchy always has the same value as its VSHPROPID_ProjectIDGuid property.
The SharedMSBuildFilesManagerHierarchy project supports the VSHPROPID_SharedProjectHierarchy and VSHPROPID_SharedAssetsProject properties for each of its shared MSBuild file project items.
