It's great to see that ASP.NET tools are finally surfacing that leverage the same code-generation capabilities as Ruby-on-Rails. ASP.NET ActionPack (http://www.codeplex.com/Wiki/View.aspx?ProjectName=actionpack) is one such example that builds data-access and presentation scaffolding. Like RoR, ASP.NET ActionPack will automatically build admin screens for all your basic CRUD fuctionality; unlike RoR, ASP.NET ActionPack will even look for foreign keys within your DB schema and provide drop-down options to populate those foreign key values. What the 10-minute webcast does not show is how to add methods to a pre-generated class - I'll assume/suggest partial classes are leveraged here. Additionally, it does not go into details concerning modifications to the presentation scaffolding. But overall, it looks to be headed in the right direction and I look forward to seeing how it evolves.
