Whatever happened to ironpython? I used to do a lot of C# development and remember dabbling with ironpython back in the day. It seemed like it was important to Microsoft, .Net added the whole concept of dynamic data types mostly to support ironpython and ironruby. But I never really used python much until recently, so of course when I finally needed to do python I looked for ironpython and it doesn’t appear to be a thing anymore.

It looks like Microsoft abandoned these dynamic language implementations in 2010. Maintaining parallel implementations of two complex, mature scripting languages is a huge feat. It would take some very expensive talent. That said, IronPython was loved by those who used it, which means it captured them in the DotNet ecosystem. Perhaps that win was not enough for Microsoft to continue the project. Ideally, Python foundation should "own" (and fund) Jython and IronPython development, but that takes (a lot of) money. (Sorry, I'm much less familiar with Ruby and IronRuby.)

It is still a thing, but it's open source now instead of maintained by Microsoft. There was a release that finally supports Python 3 in December last year.

I don't know how useful it is really, if you really want performance then you probably shouldn't choose Python to begin with, or you use the libraries which may not be compatible with IronPython. These days it barely takes me longer to build a simple script in C# than in Python either.

It's so so. Pythons core value is it's huge stack of lib's. And most important fall down with IP due to them using c and so on.

When we needed python c# interop it was better to use python.net and integrate that way. Annoying to setup but when it works you can get both to work seamlessly
