I built my EF Model in EF 4.0, and then installed the 4.1 upgrade that includes the new DBContext interface. How do I update my model so that it uses the 4.1 features going forward?
Thank You

You can use DbContext with your EDMX model. After installing EFv4.1 you should have new T4 template available: DbContext generator. This will take your EDMX and create context derived from
DbContextand all POCO entities for you. Here you have walkthrough.But if you want to switch to
DbContextjust because ofDbContext.Entry.Stateyou don’t have to. EFv4 has a similar mechanism:Here is the full description how to update an entity in EFv4.
