This interface provides internal-only access to project configuration properties. For more information, see Accessing Project Type Specific Project, Project Item, and Configuration Properties.
Assembly: VslangProj90 (in VslangProj90.dll)
External components can access these properties through the Properties collection for the appropriate Visual Studio automation object. (That is, ProjectItem for project files and folders, Project for projects, and Configuration for configurations). The property names for the members of this type can be used as an indexer into the Properties collection. For more information about accessing project properties through automation, see Accessing Project Type Specific Project, Project Item, and Configuration Properties.
