Answer 1

You need a parameter with Direction set to ParameterDirection.ReturnValue in code but no need to add an extra parameter in SP. Try this

  SqlParameter returnParameter = cmd.Parameters.Add("RetVal", SqlDbType.Int);
  returnParameter.Direction = ParameterDirection.ReturnValue;
  cmd.ExecuteNonQuery();

  int id = (int) returnParameter.Value;
