"Python’s clean object-oriented design, dynamic nature, richness of expression, ease of use, and concise syntax has won over many users in the last several years. IronPython is an implementation of the Python programming language running on the .NET Framework. It is well integrated with the rest of the .NET Framework and makes all .NET libraries easily available to Python programmers, while maintaining full compatibility with the Python language. To learn more about IronPython and to download the complete source code, please visit www.codeplex.com/ironpython.

Managed JScript is a preliminary implementation of JScript (the Microsoft implementation of ECMAScript) as a dynamic language. Implementations of Ruby and Visual Basic are under development. Future releases will expose hosting interfaces and the API for integrating other languages.

Note   Managed JScript is a separate language implementation from JScript.NET. JScript.NET is a version of JScript for managed code, but it is not a true dynamic language.

In the ASP.NET Futures (May 2007) release, support for dynamic languages in ASP.NET expands on the earlier support for IronPython for ASP.NET. Support for dynamic languages in ASP.NET is built on the Dynamic Language Runtime (DLR), a new platform currently under development at Microsoft. The DLR simplifies hosting dynamic languages on the common language runtime."
