Unpaired value in UriTemplate works on one computer, but not another

Question

In my web service I have to recieve HTTP request over a URI of the form /a?b:

[OperationContract]
[WebInvoke(UriTemplate = "http://hostname/.../a?b")]
Stream MethodName(Stream stream);

without the typical ?b=c.

This works fine on my development computer, running Windows Vista and .NET 3.5 SP1 (and adding URLACLs). However when attempting to host this op on a machine with Windows Server 2003 (.NET 3.5 w/ no SP), I get an InvalidOperationException telling me the URI template is not valid and that each portion of the query string must be of the form 'name=value'. If absolutely necessary, the client program can be changed to match a more compatible URI, but are there any remedies or work around for this?

Answer 1

You could try installing 3.5 SP1 on your windows server machine. SP1 has new functionality not just bug fixes.
