I downloaded the sample app from Karl Shifflett blog (

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. (

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.

Kindly help.

Hi Goldy,

We've examined the solution you've provided, and found that the exceptions that occur when loading the modules using a XAML module catalog dissapear if Application Library Caching is disabled.

Let us know if you keep experiencing problems with that application.

I hope you find this helpful.
