This document summarizes a presentation given by Nikos Dimitrakopoulos on the .NET Ruby VM called IronRuby. IronRuby implements a Ruby interpreter that runs on the .NET Common Language Runtime. It allows Ruby code to easily interface with .NET libraries and be deployed on .NET infrastructure. Some key benefits highlighted include the ability to test .NET code with Ruby testing frameworks, extend existing .NET classes from Ruby, and take advantage of the large .NET library ecosystem and services like Azure. Limitations include a lack of support for native C gems and some rough interoperability edges. The status of IronRuby is mentioned as having reached an RC1 release running on .NET 3.5/4.0 and
