I created a quick video to help you get started with using Jounce. The video starts with a blank slate, steps through installation of Jounce and the creation of a sample view model for a simple contact record that includes validation. You can access the video directly at http://vimeo.com/jeremylikness/jounce-getting-started, or view it below: ...

I thought it might be useful for users (and potential users) of Jounce, MVVM, and Silverlight in general if I were to show the full process of building an application. When people ask me about how complicated MVVM is, I reply ''it's easy when you know it and use the right framework.'' I hope this video illustrates that. I also find Silverlight in ...

One common request I get is how Jounce can work with the Navigation Framework. My first reply is always, ''Why do you want to use that?'' As you can see in previous posts, the Jounce navigation works perfectly fine with region management to manage your needs. If you want the user to be able to ''deep link'' to a page, you can easily process the ...

Now that we've explored the concept of Jounce navigation, the next logical step is to examine region management. This concept was introduced by the Prism framework and is very powerful and functional for both WPF and Silverlight applications. Region management deals with a few moving pieces. A region is simply an area of the display that has ...

Over the next few weeks I will be publishing a series of posts explaining the open source Jounce project that I just released. Jounce provides guidance for building modular Silverlight applications using the Managed Extensibility Framework (MEF) and Model-View-ViewModel (MVVM). Origins I have been building enterprise Silverlight applications ...

After having worked on several major projects that integrated the Managed Extensibility Framework, I thought it might be beneficial to share a retrospective on how it was used what value it provided. These are all ways MEF helped my team build modular Silverlight applications. Unlike my earlier post that covered 10 Reasons to use the Managed ...

A slide deck for an introduction to the Model-View-ViewModel pattern.

Example of an application before and after refactoring to use the MVVM pattern.

Thanks to everyone who joined me last night for my presentation about Model-View-ViewModel for the Atlanta Silverlight Meetup group. I enjoyed it and appreciate you sticking through the heat (pardon the pun). As promised, I've uploaded both the slide deck and the code that I demonstrated for you to work with. Click here to download the slide ...

The Managed Extensibility Framework (MEF) is a very powerful tool for building modular, extensible Silverlight applications. If you've followed this blog, you'll know that it is not just for applications that anticipate plug-ins, but can be used as an inversion of control container, can facilitate region management, and much more. In preparing the ...
