The real type behind a System.__ComObject
Carlos posted some time ago a really interesting article on how to find the real object type behind a System.__ComObject. The .Object property of many classes of the Visual Studio Automation model returns this System.__ComObject type.
This is really useful and can save a lot of time when you need to debug your VSX Package or GAT Package. As Carlos pointed out you will need to add a reference to the Microsoft.VisualBasic.dll assembly, if you develop using the C# language you can remove this reference after you finished with the development.
