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: ...

Sometimes it makes sense to have multiple types of views contained within a list or region. In WPF, a data template selector can help determine which template is used based on the data template, allowing a container to mix different types. It's not so straightforward with Silverlight because the DataTemplateSelector class does not exist. There ...

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 ...

Navigation is always an interesting topic and something I often see people struggle with in Silverlight applications. I am not a fan of navigation methods that force you to change the way your views behave, which is why I am not a fan of the navigation framework that is built into Silverlight (you suddenly have to use pages instead of user ...

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 ...

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 ...

Published another quickstart. This is an introductory quickstart for the Managed Extensibility Framework, and is similar to the previous one except that it is specific to Silverlight. You can take a look at the article and watch the short video by clicking here.

By now, you probably are aware that you can dynamically load XAP files using the Managed Extensibility Framework (MEF) within your Silverlight applications. Have you been scratching your head, however, and wondering how on earth you would actually test something like that? It is possible, and here's a quick post to show one way you can. First, ...
