  • Lack of direction from Microsoft: Microsoft hasn't given clear directions on this pattern yet, and the various non-Microsoft resources available on the topic can send mixed messages, leaving developers and architects confused.

  • Need for boilerplate code, complicated techniques and/or frameworks: There are many areas in WPF and Silverlight where MVVM support can be improved. Things like property changed notifications and commands require lots of boilerplate code and potentially brittle designs that require using "magic strings". There are many frameworks and techniques out there that help address these issues. However, you may not want to or may not be allowed to use open source frameworks. Also, implementing the techniques that allow you to avoid using the frameworks can be complicated and require a good bit of boilerplate code to implement, as you will see later in this...
