Are there any .NET CLR/DLR implementations of ECMAScript?

Question

Does anyone know of real (i.. no vaporware) implementations of ECMAScript targeting the .NET CLR/DLR? Ideally something like what Rhino is

Answer 1

You can take a look at Jint (http://jint.codeplex.com) which is an open-source ECMAScript interpreter.
