Been working a bit with DSL and specifically a very cool tool from my company, Avanade.
Lot's of folks are hot on DSL's, and their promises, but I've seen quite a bit of promises of full-round-trip tools before. Most required so much work to keep full fidelity between model and reality that at some point we turned off the tool and just disconnected.
Now, with the model driver designer capabilities getting so readily available for Visual Studio, with DSL's as well, more people can enter the market. This will clearly lead to lots of junk out there that may just not work. But, through the masses of attempts, I'm sure a few will bubble up.
I'm hoping our Asset is that one :)
