The IronRuby team is pleased to announce the release of the IronRuby CTP for .NET 4.0 Beta 1: [http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27606](http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27606) This release corresponds with the shipping of Visual Studio 2010 Beta 1, which includes .NET 4.0 Beta 1: [http://www.microsoft.com/visualstudio/en-us/products/2010/default.mspx](http://www.microsoft.com/visualstudio/en-us/products/2010/default.mspx) This is a preview of IronRuby running under the Dynamic Language Runtime, whichis is built directly into .NET 4.0! 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: [http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27320](http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27320) - The IronRuby Team ---

Is there a plan to allow users to build from source and still run within VS2010? Ryan R. removed\_email\_address@domain.invalid [http://panesofglass.org/](http://panesofglass.org/) [http://wizardsofsmart.net/](http://wizardsofsmart.net/) On Wed, May 20, 2009 at 10:23 PM, Jimmy S. \< ---

Nothing stopping me, just wondering if something already existed. 🙂 Ryan R. removed\_email\_address@domain.invalid [http://panesofglass.org/](http://panesofglass.org/) [http://wizardsofsmart.net/](http://wizardsofsmart.net/) ---

The Developer Division source tree was branched over a month ago in preparation for the beta release. Ruby and DLR development continued on the “head” branch, while stabilization and fixes were applied to the “beta 1” branch. Because of this, there’s some chance that changes have been made to either Ruby or the (non-core) DLR which prevent Ruby head from working with the beta 1 CLR. In other words, this would require a bit of work – first to identify whether or not any changes are needed to work with the older version, and then to actually make a branch on github and do that work. In other words, this is basically a resourcing problem – and IronRuby doesn’t really have any Microsoft resources to spare for something that is essentially “dead-end” work. But anything that could possibly be needed to do this work is publicly available and open sourced. So in short, our plan is to let you do the work! 🙂 You have the source – what’s stopping you?!

FYI there was an issue with ir.exe.config which stopped ir.exe from running properly: the issue is now fixed, so if you experienced this please re-download this release: [http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27606](http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27606) ~js
