Unable to find the relationship type in the metadata.

This method is intended to be used in scenarios where the user does not have full metadata, including the static type information for both ends of the relationship. This metadata is specified in the EdmRelationshipAttribute object on each entity type in the relationship, so the metadata system can retrieve it based on the supplied relationship name and target role name.

The relationship name should not be namespace qualified. An error occurs when you prepend the namespace to the relationship name.
