Web Client Software Factory Fix for Add View with Presenter Recipe
The team was finally able to find a fix for this sporadic issue: occasionally the Add View with Presenter recipe would throw a ValueProviderException. This was apparently due to having two versions of the same DLLs loaded in memory at the same time. The Recipes were built with a signed version of the DLL, but the projects were loaded with an unsigned, source version of the DLL. There is a full explanation of the issue, and also a fix on our known issues page.
