Hi

Unfortunately, the latest forms update has totally broken my project (thankfully I have a backup). It seems that every time I update forms it breaks my application in some way.

I have tried the various suggestions online such as deleting obj and bin folders for the project and, and removing the [XamlCompilation(XamlCompilationOptions.Compile)] from the code-behind, to no avail. Still wont build.

Anyone have any idea how to solve this - I am guessing it has effected like everyone using forms...
