We have also discovered this project. This is actually a port from the Java code, and almost does the same things as Jint. Though, if I had to tell someone the advantages of Jint, I would say security. With Jint you can set permissions based on CAS, and by default nobody can for instance call System.Directory.Delete(). You have a granular way to open restrictions.

I would also like to comment the statement "really interpret js". Do you think Jint doesn't interpret js ? It does ! What is your point of view ?

Finally we also aim at implementing ECMAScript 5. Don't know what is the plan for this project.

about "really interpret js", it means no offensive, just because I saw the same statement on your project's home page. and both of it and your project are not codedom related.

The key difference between Jint and ecmascript.net is that Jint is being actively developed, and Sebastien is active with the community.  Ecmascript.net appears to be abandoned, so I would anticipate that you're "on your own" if you have problems.

How strong is your need to use JavaScript from C#?  The only real alternative to Jint is Rhino, using the techniques that I describe here:  http://www.codeproject.com/KB/cs/EmbeddingJSCS.aspx.  (The disadvantage of my technique is that it really only works well on mono, which is why I'm keeping an eye on Jint.)

We also handle generic types now (next release). For instance you can do:

var list = new System.Collections.Generic.List{System.Int32}();
var squares = list.ConvertAll{System.Double}( function (x) { return x*x; });


It's might not be interesting to execute standard JS, but for scripting your application it's cool IMHO.
