Comments: I created a prototype which is a T4 template that should help define the API for generating views in EF6. More details here: http://blog.3d-logic.com/2012/10/17/entity-framework-6-and-pre-generated-views/. The template is on VS Code Gallery http://visualstudiogallery.msdn.microsoft.com/18a7db90-6705-4d19-9dd1-0a6c23d0751f
