Entity Designer: Improve Model First to preserve user intent (aka support Migrations for EDMX)
The "Generate Database from Model" feature is referred to as Model First. There are functions in the power pack (http://bit.ly/8akJIs) to incrementally update my database from my model but it doesn't fully preserve user intent. For example, if I rename an Entity, I just want to rename the table, not drop the table and its data and add it again.
Closing this as it is specific to EF6 and/or EF6 designer and we are now only tracking EF Core ideas here. If this is important to you, create an issue at http://github.com/aspnet/entityframework6/issues/new, but keep in mind that moving forward, our team will only fix bugs, implement small improvements and accept community contributions in the EF6 codebase.
