The process of passing credentials via wcf was a major pain. This article seems to have addressed the issues quite nicely. I was able to get the sample app working right away.

But, when I copy the app/web.config settings to my own project, using the same certificate, the service call fails with the error:
“Content Type application/soap+xml; charset=utf-8 was not supported by service http://slcdevelopment/slcservices/slcservices.svc. The client and service bindings may be mismatched. “”

The bindings on both ends are exactly the same as in the demo. When I switch my project back to use basichttpbinding, it works fine.

I put a breakpoint in the Myx509Validator method, and that does not seem to be even reached.

Are there any “usual suspects” that can cause something like this to happen?
Thanks for the great work!
