SharePoint 2007: .asmx was not recognized as a known document type.
I am interfacing with a SharePoint 2007 farm via web service. I tried adding the _vti_bin/webs.asmx as a service reference when the following error: The document at the url http://blah.com/_vti_bin/webs.asmx was not recognized as a known document type. Fortunately, there is a simple solution to the problem: add ?wsdl to the url and the problem is resolved.
