The incoming tabular data stream (TDS) remote procedure call stream is sending an unlimited length CLR type. Parameter %1!s! ("%2!s!") is defined as type %3!s!. This type is not supported by down-level clients. Send the serialized data of the large CLR type as varbinary(max), or upgrade the client driver to one that supports unlimited CLR types.
