Why is the .NET SDK throwing exception "Client found response content type of 'text/html; charset=iso-8859-1', but expected 'text/xml'"?
If the SDK encounters an response whose type is not text/xml, then it throws that exception. The best way to find out what is causing the error is to turn on logging and see what is actually sent and received.
