There doesn't appear to be any way of specifying the SOAP version (though the client can automatically determine this AFAIK)
When receiving a 1.2 response this exception is thrown:
InvalidOperationException: <Envelope xmlns='http://www.w3.org/2003/05/soap-envelope'> was not expected.
There is a closed issue for this but the comments trail seems to suggest other people aren't seeing this support either
