Trying to run a WCF service in Cassini on your Windows 7 Beta (7000) machine and get this error?

The remote server returned an unexpected response: (400) Bad Request.

Unless you’re running your service with basic http binding or with security specifically set to None in your bindings, you will get this security-related error. This problem was confirmed by Microsoft and will (hopefully) be fixed in next Windows 7 release.

The options you got:

• Create and run your own service host with code (I’ve been doing this in my integration tests until I tried Cassini and got the error)
• Use IIS (which I’m going to go for)
• Self-host it with WcfSvcHost.exe (which I’ve not tried yet)

Note that you need to add quite a few features to get WCF running in IIS running on Windows 7. See my previous post about this.
