I can't seem to get even the simplest WCF Service working. May be something with my setup, I'm hoping you guys know. My service opens without errors in IE when I press Ctrl+F5. If I copy the URL, start wcftestclient.exe and paste the URL, I get a nice interface with the operations defined in my ServiceContract. So far so good. When I try to use one of the operations though, I get the following error message:
"The remote server returned an unexpected response: (400) Bad Request."

I'm running the Windows 7 Beta, could that be the problem? Or is this something completely different. I'm lost here, so any help is appreciated.
