The .NET Framework 4.0 and Visual Studio 2010 Beta 1 is now generally available for download. Jason Zander has a very thorough rundown on some of the new features in this release. Of course, my favorite new features in VS2010 is the new dynamic language support in C# and Visual Basic, which let’s you easily call out to IronPython code from those languages.
For anyone who wants to experiment with interoperating C# or VB with IronPython, we released IronPython 2.6 CTP for .NET 4.0 Beta 1 today. There’s also a walkthru showing how you can use the standard Python library module random from both C# and VB. Note, there’s currently a URL bug in that walkthru – it links to IronPython 2.6 Alpha 1 rather than the .NET 4.0 Beta 1 IronPython CTP. Make sure you pick up the right version of IronPython if you want to try out the walkthru. Looks like they fixed the redirect in the walkthru.
FYI, this is a CTP quality release with about the same functionality as IronPython 2.6 Alpha 1. Essentially, this is the version of IronPython that was in the source tree when the VS team branched for Beta 1.
