silverlight 4 net tcp binding security

Question

This document talks about how to send username and password from SL4 app to a web service.

It assumes that HTTPS will be used for transport. However, I want to use NET TCP because of its speed. Is that possible because another article says net tcp in SL4 does not provide transport level security. If that's incorrect then how do I convert the https implementation to net tcp?

Answer 1

Silverlight 4's Net.TCP connections don't support transport level security and Silverlight itself doesn't support message protection (see the comments on http://tomasz.janczuk.org/2009/11/wcf-nettcp-protocol-in-silverlight-4.html).

To answer your question: if you want a secure connection you must use HTTPS.
