- Prefer C# by far.
- Do C/C++ and some Java at work. I do write some work related test tools in C#.
- All pet projects are in C# although I also have a pet project that involves a mix of C# and ARM assembly (.Net -> ARM crosscompiler).
- I worked for a short amount of time on a Flex/Java project at work, but fortunately was able to get out of that one after I realized how horrific the development environment was.
