Visual Studio Tools for Applications 2.0
Microsoft Visual Studio Tools for Applications 2.0 gives you a way to enable end users to customize your existing applications using Visual Basic and Visual C#. You can incorporate a custom integrated development environment (IDE) that is similar to the Visual Studio IDE into the application. End-user developers can use the IDE to customize the application by creating add-ins that extend the functionality of the application to meet their needs.
