A class in the Microsoft® .NET Framework or a member of such a class that is created when processing a COM coclass that managed code requires to interoperate with the corresponding COM object. Use this class only when you must access an earlier event in this class that has been extended in a later version of the product. Otherwise, use the interface in the .NET Framework that is derived from the COM coclass.
For information about the .NET interface, see Master.
