For all of you who want to further understand the inner workings of BDD 2007, the source code is now available!
This means that you can make modifications, enhancements or perhaps even fix bugs!!
If you feel the urge to make changes to the source code for your own use be aware that you may need to reengineer these changes when upgrading to the next version of BDD.
Anyway I know some folks have been waiting for this for a while, so go and have a play with it at least.
The code has been released under the Microsoft Permissive Use license.
