InsertOrUpdate not return id

[ignasivs]

When I use the InsertOrUpdate function of the Rainbow, it returns 1 when it inserts and 2 when it updates. How can I get the id of the object that has been updated or inserted?

I have the version of dapper 1.50.2 and of Rainbow.MySql 0.10.1

Code:

public static Tuple<int, int> AddOrUpdateSesionCarrera(sesiones sesion, out Pk15Error pk15error)
        {
            pk15error = new Pk15Error();
            try
            {
                using (var transaction = new TransactionScope())
                {
                    // Operaciones sobre la base de datos.
                    Db newdb = IVS_OpenConnection.db;
                    OpenConnectionInstance connect = null;
                    if (!string.IsNullOrEmpty(IVS_OpenConnection.CadenaConexion))
                    {
                        connect = new OpenConnectionInstance(IVS_OpenConnection.CadenaConexion);
                        newdb = connect.db;
                    }

                    if (sesion.carrera != null)  
                    {
                        var sesionId = newdb.Sesiones.InsertOrUpdate(sesion); //TODO InsertOrUpdate not return id.
                        sesion.carrera.idSesion = (int)sesionId;
                        var carreraId = newdb.Carrera.InsertOrUpdate(sesion.carrera);
                        connect?.Dispose();
                        /* Devolvemos el id de la sesion */
                        return new Tuple<int, int>((int)sesionId, (int)carreraId);
                    }

                    // Aceptamos la transacción.
                    transaction.Complete();
                }
            }
            catch (OpenConexionDbException e)
            {
                pk15error.exception = e;
                pk15error.errorType = EnumeradosIVS.TDapperError.DatabaseConnection;
                return null;
            }
            catch (Exception e)
            {
                pk15error.exception = e;
                pk15error.errorType = EnumeradosIVS.TDapperError.DatabaseQuery;
                error.EscribeErrorBD("Error AddSesionCarrera: " + e.Message);
                throw new Exception("Error AddSesionCarrera: " + e.Message);
            }
            return null;
        }

Thank you @antonheryanto

there is 3 API for InsertOrUpdate

InsertOrUpdate(Id, new { Name = "test" }); //return Id  (means param id first 0 than assigned the autoincrement value
InsertOrUpdate(new {UserId}, new { Name = "test" }); //using key other than id (UserId here) 
InsertOrUpdate(new { Name = "test" }); //which will return db.Execute return (affected row)

so in your case in order to get sesion Id uses

var sesionId = newdb.Sesiones.InsertOrUpdate(sesion.Id, sesion);
