Is the Entity Framework aware of identity columns?
I am using SQL Server 2005 Express Edition and have several tables where the primary key is an identity column. w
You should set the identity columns' identity specification so that the (Is Identity) property is set to true. You can do this in your table designer in SSMS. Then you may need to update the entity data model.
Perhaps that what you mean by saying the "Primary key is an identity column," or perhaps you missed this step.
