WCF Test client and authentication

Question

I'm trying to call a webservice with WCF Test Client but the webservice requires authentication.

How do I log on and call it by WCF Test Client (I tried to get it from browsers and then to call but does not work). I could use SOAP UI, but I'd like to do it with WCF Test Client if is possible. Maybe changing WCF config?

Answer 1

Do you have a mex endpoint specified in your config?

If you're having setup issues I'd suggest reading through the Codeplex applications scenarios to ensure you have setup your service and WCF Test Client properly.

Please post configs and some sample code if you require any further help.
