Question

I want to allow my users to use a script language to further customize my application.
I´m looking for an embeddable script engine that is thread safe, because it´s a ASP.NET application. I Checked some engines, like Javascript.NET (https://github.com/JavascriptNet/Javascript.Net ) but it is not Thread safe. Other implementations I found do not look stable enough.

Any sugestions ?

Thank you,

Perhaps IronPython or IronRuby under the DLR is suitable?

You can mark up your extension points using MEF, and allow scripts to extend your application’s functionality.

We’ve used it successfully in MahTweets (a WPF Application) – but I can’t vouch for it’s use under an ASP.NET situation.

Of course, thread safety is going to be your least concern if you’re allowing random people to run arbitrary code within your application. They’ll have full capabilities to completely bypass any security functionality you have, and alter/copy any user data.
