I sell a C#/WPF application (targeting .net 3.0 at the moment) and people keep asking me for a Mac version.
The application is a time tracking application with a good GUI, there isn't that much business logic in a time tracking application so most of the application is GUI - rewriting just the GUI is equivalent to rewriting the entire application
I don't have the resources to rewrite the application or maintain two different code bases, so I need a way to run the same code on a Mac (I know I'll have to debug and modify the code, what I mean is I can support only one code base, I can't split the project into different Mac and Windows projects - I just don't have the time to work on two projects).
Porting the application to a cross-platform UI library, to a different programing language or to Silverlight are all not relevant - it will take too much time and I think I'll get more sales by investing this time in new features.
Does anyone know of a tool that can run or port C#/WPF to the Mac?
There's absolutely no way you can run full-fledged WPF app on Mac. I'm not even sure if this is possible in Parallels. The best thing you can do is to use Silverlight, which was previously named "WPF/E" and does run on Macintosh.
