I'm just wondering if anyone out there has tried running a WPF app that uses PRISM from a button add-in in ArcMap. The OnClick event goes as far as initializing and showing the Shell.xaml but when it tries to load the modules and the controls in the regions, I get this error:
"Unable to cast transparent proxy to type 'InnerModuleInfoLoader'"
Please disregard this, I found the resolution for this. ArcMap was just telling me that it couldn't find the Prism DLLs, that's all. After registering them in the GAC, the WPF app ran without a hitch.
