Download Assembly on Demand Sample

This sample has defined a common interface type that is shared between the type in the downloaded assembly and the assemblies that reside within the XAP file.

So I don't need to use Reflection to perform late-binding calls (but I do use Activator.CreateInstance to create an instance of the type downloaded). First Press the Download button to copy the UtilityLibrary.dll from the site (under ClientBin where the XAP is downloaded from), then press the Use button. Source:
