SET IDENTITY_INSERT [users] ON

But it's not relevant for EF, as i see, you have used

"I get the following error: Cannot insert explicit value for identity column in table 'People' when IDENTITY_INSERT is set to OFF."*

I think that the IDENTITY_INSERT is the Auto Increment functionality which is off. So, check the field PersonId in the database to see if it is an identity.

Besides, maybe this will fix your problem too.

C#

[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }

The problem lies in the AddToUtilisateurs method, without this I cannot be 100% certain what is wrong.

Given the error message you describe somewhere along the line you are trying to an object's data where the record already exists. In your case to the object is being persisted in the users table. What is happening is the User object (UtilisateurCree?) already has an Id (probably the primary key on the table) set, whereas the database is expecting to generate it for you. If you are updating an existing user, you will need to get the user object from the data store, update the information and save, rather than trying to re-add it.
