Book review Silverlight 4 Business Intelligence Software

I've written a review of this book on amazon. Gist of it is that it's a solid book that focuses on BI issues mostly. It does not go into any Enterprise patterns. Here's the link

Really Good MVVM articles on Msdn

Many of you have probably already seen this, but if you haven't these are the best non-video articles I've seen yet on MVVM in general and with Microsoft Prism. This first article is a fantastic introduction, http://msdn.microsoft.com/en-us/library/gg405484(v=PandP.40).aspx, that is specific to MVVM and deliberately omits most of the Prism stuff to keep things clear and simple. This next article, http://msdn.microsoft.com/en-us/library/gg405494(v=PandP.40).aspx, goes deeper into the pattern and gets into specifics where the Prism library can help you implement a better MVVM. I think this quote from this chapter says it all, "The previous chapter described how to implement the basic elements of the Model-View-ViewModel (MVVM) pattern by separating your application's user interface (UI), presentation logic, and business logic into three separate classes (the view, view model, and model), implementing the interactions between those classes (through data binding, commands, and data validation interfaces), and by implementing a strategy to handle construction and wire-up."
