Hi,
The issue you are facing is related to having the new downloaded source code on the same folder location that Prism 4.1 was before. By doing this, the solution would find the old Prism 4.1 assemblies that were built before, making it to throw a versioning error as Prism 4.1 old assemblies were configured for Net 4.0.
In order to solve the problem, extract the Prism 4.2 zipped folder into a new empty folder and build the Prism Library solution. Notice that Blend for Net 4.5 would be needed to be installed in the machine which it would actually be installed automatically with Visual Studio's update.
I hope this helps,
Regards.
