I just started using EF5. I created a MSSQL database, then I created the model (edmx) file and then used the “Add code generation item” to create EF5 dbcontext classes.

Whenever I alter my database (adding a column or changing a datatype) I see that “update model from database” doesn’t work and I need to delete and recreate the model.
that’s ok for me but what happens to my DbContext classes generated from the model.tt template file? do I have to generate all the DbContext classes again also?

what’s the correct way to work with a database-first environment and keep the .edmx model and the DbContext classes in sync with the database?
