Where can I find CSharpEvaluator?

What Anders presents at minute 60 of this vid开发者_开发知识库eo seems pretty cool

However, I can't find it. Is it released? Is there an alternative?

I understood that it was not released. There is actually an alternative which for me does same thing. and was there for years

I thought it was in mono. (mono.sharp) (can't watch the video, I'm currently at an evening course so I might be thinking about the wrong CSharpEvaluator)
