Linq to SQL: Why am I getting IDENTITY_INSERT errors?

Question

I\'m using Linq to SQL. I have a DataContext against which I am .SubmitChanges()\'ing. There is an error inserting the identity field:

Cannot insert explicit value for         


        

Answer 1

My theory of what happened is as follows:

1. You designed and created the DataBase
2. You created the DB Context using LINQ TO SQL in visual Studio
3. You forgot to set the auto-identity to your table
4. You fixed that by going to your DataBase and setting the auto-identity
5. But you forgot to recreate/update your LINQ TO SQL DB Context!!!
