Quick .NET Web Reference Note

Apparently setting the URL property of a web service proxy class resets the Credentials property to the default. This means that if you're setting both, make sure to set URL and then Credentials. Intuitively I guess this would make sense if the pattern of use involved reusing the same proxy for calls to identical services in different locations. Given that in reality you usually create the proxy, optionally set properties like URL and Credentials, make some calls, and ditch the proxy, I don't know why that behavior exists.
