With “Simplified MVVM” you can simply place your web service methods in your Model. The problem you run into, is how do you make an asynchronous web service call and fill a collection in your ViewModel? One method I have employed in the past is to pass an instance of the ViewModel to the Model, however, the problem this causes, is that you have now tightly coupled your ViewModel and your Model. It is also difficult to consume your Model from multiple ViewModels when you do it this way.

A while back I made a post about using Windows Authentication with RIA Services and this post builds upon the topics discussed there. To further complicate the situation I needed to deploy a RIA services app to a Virtual Directory inside of a sub-folder in the IIS web root.

After months of work by Michael and myself, I am happy to announce that Building Websites with DotNetNuke 5 has been published! They have also published a snippet from chapter 6 – Understanding the DotNetNuke Core Architecture: https://www.packtpub.com/article/understanding-dotnetnuke-core-architecture-1 (Somehow Michael convinced them to give him all the credit for the chapter I wrote, but I won’t hold it against him. :P)

The book covers DNN from installation, management, development and deployment. Michael provides some excellent information on how to use Silverlight with DotNetNuke that makes this book worth reading just for that! Anyway, this is not meant to be an advertisement, just an excited post that the book is officially completed and now available! Writing the book was a neat experience and the fact that both of the authors are OpenLight Group founders made it that much better.

If you are interested...
