Question

I am using Entity Framework 4.1 code first. I have a product table that has an Id column that is an auto incremented column. When I add the the Product instance, how do I get this new id or the updated Product (returned with properties)?

My repository code:

MyContext db = new MyContext();

public void Insert(Product product)
{
     db.Products.Add(product);
     db.SaveChanges();
}

Answer 1

After performing the insert look at the product.Id property (or whatever your id property is called). It will be updated by EF with the value assigned by the database.
