MSDN’s main page is covered in purple and full of more links than you have time to click on, so you can check out everything there too.

The C# compiler and the support for dynamic, including the DLR, come in the box on every distribution of the .NET Framework 4.0. And also, of course, with every edition of Visual Studio. In addition to that, you’re going to want to use C# dynamic with some good dynamic languages. Happily, IronPython has released a final version (2.6.1) built for use with .NET 4.0. Check it out!

Thanks!

UPDATE: It wasn’t up when I posted this, but now IronRuby has also pushed a final build (1.0) that runs on top of the released .NET 4.0!
