Message in Russian (Русский)
Невозможно добавить тип "<var>Type Name</var>" в список известных типов, так как уже имеется тип "<var>X</var>" с тем же именем контракта данных "<var>Y</var>:X".
Unlocalized message
Type '<var>Type Name</var>' cannot be added to list of known types since another type '<var>X</var>' with the same data contract name '<var>Y</var>:X' is already present. If there are different collections of a particular type - for example, List<test> and Test[], they cannot both be added as known types. Consider specifying only one of these types for addition to the known types list.</test>
