--- Comment #13 from Esme Povirk madewokherd@gmail.com --- With current Wine Mono, I get a couple of NotImplementedExceptions, one in WindowsIdentity.get_User (which we seemingly already have duplicate bugs for: bug 25167 and bug 32266) and one in WindowsFormsApplicationBase.OnCreateMainForm. I know WindowsFormsApplicationBase is missing a lot of functionality but have been having trouble finding a test case (bug 32760 says this but does not have a test case).
Not sure how to classify this bug since the application may depend on both of these, or neither. Or maybe this bug should be considered fixed since the WPF error no longer occurs, and the other bugs should be updated to indicate that this application is affected.
