Then, he was working on a WPF project with five other developers and needed an MVVM-framework since the application was not using MVVM at the moment. Writing an MVVM-framework was no option because there were so many other frameworks out there. But, after looking at some Open-Source MVVM-frameworks (such as the excellent Cinch framework, which was the best one we could find), none of them seemed to be a real option. Creating the View Models was too much work, and the View Models still contained lots of repetitive code in, for example, the property definitions. After taking a closer look at the source code of Cinch and other frameworks, the lead developer thought: if we use the DataObjectBase published before as the base for a View Model class, it should be possible to create a framework in a very short amount of time.
