Description
I have a simple user class,
public class User
{
[Key]
public GUID UserId {get; set;}
public string Firstname {get; set;}
public string Lastnmae {get; set;}
}
When I call Insert(user) mehtod, alwasy return 0;
But I put user in list
List users = new List(); users.add(user);
and then call Insert(users) return 1;
I don't know why.....Thanks for your help!

Research direction
Start by reproducing the issue with the User class and the single-object Insert(user) and list-based Insert(users) entry points described in the report. Compare their return values with the database state, then inspect the relevant insert implementation to determine why the two calls differ. Done means the single-object insert returns the expected result while still inserting the record successfully.
