I have a known working web service which is configured as a SOAP and REST binding. I can call it with a test harness and I can see the SOAP POST’s going to and then the SOAP response all good.
However when I try and host the service in visual studio 2010 Cassini I get the following behaviour:
1) When calling endpoint as REST and using the WebChannelFactory class the service works.
2) When calling the endpoint as SOAP and using the ChannelFactory class the service throws an error and I get a 400 response. (The error is below).
3) When calling the endpoint as SOAP and using a c# SOAP reference the service works.
Confusing no?
Im wondering is it something to do with the fact that I have used a port number for the Cassini version?
just before people start telling me to host in IIS I really need to get this working in Cassini as its part of a tutorial on WCF
Here is the raw HTTP request that doesnt work (when called against a working IIS deployment and the faulty Visual Studio webserver.

*******Update*************
Whilst the answer to this question was correct. My testing wasnt. I actually tried to pass a ‘//’ in the url for the IIS and Cassini and it didnt work for Cassini. Obviously IIS is a bit more robust when handling quotes. The comments below talk about this but I thought i would update the answer.
The first line of your “not working” request has an extra slash in the URL:
