I downloaded the sample app from Karl Shifflett blog (http://blogs.msdn.com/b/kashiffl/archive/2010/10/05/integrating-prism-v4-region-navigation-with-silverlight-frame-navigation.aspx)
Based on this app I created my new sample app as i wanted to integrate the modules download on demand. For this I was referring to Prism Quick start apps that comes with Prism download (ModularitywithMef in Silverlight).
I am getting lot of errors, when I apply this logic. You can download the sample app from this url and help me to trouble shoot it. (http://cid-e84cfb62692563c4.office.live.com/self.aspx/.Public/PrismwithRia.rar)
If you see the solution there are two modules (Masters and Orders). The masters module is directly reference in the application and hence it works but for orders i want to load it on demand , by clicking on the hyperlink button. I have configure the ondemand
download in xaml file (Catalogs.xaml).
Please let me know if you need any further info.
