Wanted to make people aware of the excellent work two of our MVPs ( Pascal Recchia and Anthony Guerot ) have done recently with the DSL Toolkit. Checkout this great article on how they have manipulated the DSL API in order to get multiple views over a single store. They have also provided access to a video showing the functionality, as well as the code they created.
This is great stuff, and does show the power of the DSL framework that we have built the UML designers coming in VSTS 2010 on.
With the 2010 product, we hope to make this type of functionality even easier, with even more extensibility options possible with new APIs we will be providing.
