I did a lot of C#/.NET dev a few years ago while working for an IB. Started my own SaaS business recently which is mostly built in Python. As my product is quite heavily related to the Microsoft world .NET was the best fit for my backend workers so I ended up doing a lot of stuff in IronPython. I know it's still actively being developed by a few volunteers after MS dropped it back in 2010 but it feels like it's a very small community. Any other IronPython guys here on HN and what do you use it for?
