Last I’d heard IronRuby was mostly dead, and I’m sure it wasn’t written to fit this new “dynamic language runtime” Microsoft has announced. I’d wager they co-opted the name from Wilco and are running with their own internal implementation. - Charlie ---

I suspect it’s a merge between IronRuby and RubyCLR. Remember John L. (author of RubyCLR) now works for Microsoft, along side Jim Huginin(?) of IronPython and Jython fame. I can’t wait for the day when I can fully use RSpec for both Java and .NET projects. 😃 ---

Apparently it is a new implementation of Ruby using some of the core of IronPython and was in development before John L. arrived at Microsoft. Tim Heuer has a video interview with John that goes into more detail about the Ruby version and the Dynamic Language Runtime. Good stuff. > **[mix07: ruby for .net and an interview with john lam](https://timheuer.com/blog/post-14059)** ---

I’ll bet anyone a beer it’s all new code, unrelated to Wilco’s IronRuby and John’s RubyCLR (and even Queensland University’s [Ruby.NET](http://Ruby.NET)). - Charlie
