I am trying to update an entity directly as follows

        ServisEntity servis = new ServisEntity();
        try
        {
            servis.IsNew = false;
            servis.Serviskod = "000:2756"; // Primary key
            servis.ServisTipKod = 1;
            servis.BolgeKod = "30";
            servis.KisaUnvan = "deneme";
            servis.Unvan1 = "deneme";
            servis.Eposta = "testqtest.com";
            servis.Save();
        }
        catch (Exception hata)
        {
            Console.WriteLine(hata.Message);
        }

If there is a record with the given key value there is no error but if there is no record I am receiving the following error

"During a save action an entity's update action failed. The entity which failed is enclosed"

Hello,

is the PK an identity field?

No, it is not an identiy field, just as varchar(20)

In a first time, if you try a fetch and a save, is your entity is saved? If not, it could be another problem that the update directly. If so, could you check the ID value?

Please also enable DQE tracing and see what the query looks like that's being generated (See troubleshooting and debugging).

Also it's best to set IsNew to false right before Save(), because the change checker routine checks if an existing value is equal to the value set. In a new entity, this always succeeds, in an existing entity (IsNew == false) this only succeeds if the new value is different from the current value, otherwise IsChanged isnt' set to true.

I also tried for the other entities und olso make isnew=false just before the save() but again I am reciving the error message
