Hello dimesio,
I'm surprise My Sudoku 3.0 worked, the front end is written in WPF. After I submitted this post I obsessively searched for the issue and noted that Wine does not support WPF applications

. One work around I was considering was attaching a portable class library targeting my WPF application for Silverlight and recommending that Linux users install Moonlight along with Wine but if dotnet40 works...
Thanks you for your help, I truly appreciate you taking the time to try to run one of my apps! I'm running a 64 bit version of Ubuntu and Wine. I was trying to install dotnet40 last night but was getting an error, sorry I do not have my computer with me at the moment, stuck at my day

, so I do not recall the specific error but you may hear more from me later tonight.
However, even if this works I'm still considering attaching a portable class libary to my projects so that the GUI can run on Silverlight if WPF is not available. Do any former .Net programmers have any experience with the portable class library?
Thank you,
Joe
