The fact that its made in WPF allowes you to visualize the new features and namespaces you need to extend MS Office and create OBA’s (Office Business Applications).
The Microsoft Office interactive developer map is made in WPF so it requires the .NET Frameworks 2.0 and 3.0 to be installed on your pc.
