It may be a good idea to port your project to WinForms, as I can see that your C# programming style fits that more than WPF.
You caught me redhanded

. I haven't used WPF before this project. I said before I wouldn't port to WinForms any time soon, but I changed my mind. I have it running on Ubuntu 14.04.

It generally works, but needs some more testing before I'm confident enough to release it. It will be ready in a few days.
If anybody is feeling adventurous, you can get the source from the
github page and compile it yourself. The output of the CryptoNoteWallet.Gui project is the one you'll need. You will need to change the wallet and daemon executable names in the CryptoNoteWallet.Gui.exe.config (they don't have extensions on linux).
