En EntityContainer '<var>A</var>', no se especificó el atributo Role del extremo con EntitySet '<var>X</var>' en AssociationSet '<var>Y</var>', y hay varios extremos en la relación '<var>Z</var>' que podrían coincidir con el tipo '<var>Type Name</var>'. Proporcione el atributo Role para eliminar la ambigüedad del extremo.
