IronJS

IronJS is a ECMAScript 3.0 implementation built on top of the Dynamic Language Runtime from Microsoft which allows you to embed a javascript runtime into yor .NET applications. The current state of the code is at best alpha quality. Use at your own risk.

License

IronJS is released under the GNU General Public License v3.

Requirements

What you need to use IronJS

• An understanding that this is alpha quality software, it will crash on you.
• .NET 4.0 Beta 2, it should compile on .NET 3.5 with some minor modifications.
• The Dynamic Language Runtime from Microsoft.
