Hi All,

I have generated model from Database(Database first approach).
Then I converted a primary key columns into Identity(1,1). Now without refreshing the Model from database i would like to insert a record(e.g. db.Addobject(obj)). I mean i want to edit the edmx.cs file to accommodate this Identity field in Database.

Please help.

why would you not want to refresh the model in your entities? Its simple to just to Update Model From Database and this would solve your problem.

What is the name of your Identity column for one...that would help. It would really just be easier to do update model from database.

Thank you, David for your reply.

As you said, when i refresh from the Database I lost Data Annotations e.g. [DisplayName("Employee Name")] for EmployeeName property.

Please make a partial class and transfer all custom data annotation to there. Then update the .edmx file without any worry.

I agree with amitava...can do partial class or create ViewModels for your entities if you wanted
