Adding User via C# ChangeTrackingCollection Error

Using the following code:

 Microsoft.Azure.ActiveDirectory.GraphClient.User user = new Microsoft.Azure.ActiveDirectory.GraphClient.User();


                    userPrincipalName = "John.DoeUK@ABCDE.onmicrosoft.com";
                    user.GivenName = "John";
                    user.Surname = "Doe";
                    user.DisplayName = "John DoeUK";
                    user.UserPrincipalName = userPrincipalName;
                    user.AccountEnabled = true;
                    user.MailNickname = userPrincipalName.Split("@".ToCharArray())[0];
                    user.PasswordProfile = new PasswordProfile();
                    user.PasswordProfile.Password = "P@ssw0rd!";
                    user.PasswordProfile.ForceChangePasswordNextLogin = false;
                    user.UsageLocation = "GB";

                    graphConnection.Add<User>(user);

I get the following error after adding a new user by the code above:

JsonConverter AadJsonConverter on Microsoft.Azure.ActiveDirectory.GraphClient.ChangeTrackingCollection`1[Microsoft.Azure.ActiveDirectory.GraphClient.GraphObject] CreatedObjects is not compatible with member type ChangeTrackingCollection`1.

I corrected it once by using graphConnection.Add<User>(user) instead of graphConnection.Add(user) both now seem to be not working. The weird thing is. The user gets added to the AAD.
