WCF Error: https not supported

Hi guys,

I created a WCF service and enabled there https. Now if I call for testing purposes http://localhost:3856/Service1.svc with my webbrowser I get the message that "https is not supported". Do you have an idea why it is not supported? I'm quite confused and can't figure out why my solution does not work. As Server I do use the standard ASP.Net Developement Server which is included in Visual Studio 2008.

Best Regards,

Benjamin
