The November CTP of DSL Tools is now available for download at http://msdn.microsoft.com/vstudio/teamsystem/workshop/DSLTools/default.aspx. New features in this release include:

- A validation framework for validating the model on save, open, using a menu item, and at other custom points.
- The ability to add a DSL Setup project to your DSL solution that builds a deployable MSI for your designer.

These features are explained better in Stuart's post here. The release also includes some bug fixes.

Try it out, and let us know what you think.

Thanks,
-George
