Mono is the preferred way to run .NET apps on Wine but it may not work as well as native yet. You could try running this on Mono for Windows to see if the bug is in Wine or Mono.
Understood. I'll try Microsoft .NET before filing such bugs in the future. I've forwarded my original problem to http://bugzilla.xamarin.com/show_bug.cgi?id=772.
