--- Comment #6 from Esme Povirk madewokherd@gmail.com --- The immediate problem is that it tries to load PresentationFramework.Classic.dll version 3, and we only have a version 4. Mono has code to handle that situation, we just need to add PresentationFramework.Classic.
After that it fails because it can't find Microsoft.Windows.Themes.ClassicBorderDecorator. Which is odd because we are compiling that into PresentationFramework.Classic.
