We’re pleased to announce the release of the IronRuby CTP for .NET 4.0 Beta 1!

Download IronRuby CTP for .NET 4.0 Beta 1

This is our second preview of IronRuby running under the Dynamic Language Runtime that is built directly into a .NET 4.0 release! As before, this release allows you to use IronRuby objects and types as .NET 4.0 dynamic objects from within C# and Visual Basic code. These binaries are roughly equivalent to the functionality found in IronRuby 0.3. Please also note that the IronRuby CTP for .NET 4.0 Beta 1 will run only under .NET 4.0 Beta 1.

This release also includes the binaries for the IronPython 2.6 CTP for .NET 4.0 Beta 1.

To try out this preview release:

  1. Install some variant of .NET 4.0 Beta 1 or Visual Studio 2010 Beta 1 from here
  2. Download the release
  3. Follow any of the many dynamic walkthroughs online. Here would be a good start.

Enjoy!
