Jint is a JavaScript interpreter for .NET.

Jint is a script engine based on the JavaScript language. Using Jint, developers can provide fully scriptable applications, execute .NET code without compiling, or create external configuration logic, using the most used script language.

Jint aims at providing every JavaScript functionalities to .NET applications, and bindings to .NET languages can be done in both sides. Jint scripts can use any .NET object from your application, and use every part of the .NET base class library.

Jint has been rewritten completely and is now hosted on Github.
