After you have extracted all files from Drop 9 the Composite Application
Library source code can be found here: $ExtractionDirectory$\CAL\CompositeApplicationLibrary.sln. However if you are looking for other source code shipped with Prism-v2 it can be found:
If you are looking for the Composite Application Guidance for WPF and Silverlight Reference Implementation source code it is here: $ExtractionDirectory$\RI\StockTraderRI.sln
If you want to use the Quickstarts’ source code this is the path to find the different Quickstarts: $ExtractionDirectory$\Quickstarts\*
You could be interested in knowing that a new drop (Drop
10) has been released. In it all the aforementioned source code is in the same location.
Please let me know if this helps.
