ADO.NET vNext Entity Data Model Designer
The ADO.NET vNext team decided to release the Entity Data Model (EDM) Designer Prototype. I tried the early bits on a demo I prepared for an internal event next week and later this year at the (Dutch) Software Developer Event, 11th December 2006, Ede. It will be very interesting to see, assuming the designer is based on the current Domain Specific Language tools bits, what functionality will be embedded eventually and what effect this new technology has on the usability experience.
