I try to add a service reference to the http://www.webservicex.com/globalweather.asmx?WSDL web service. I go to Add service reference, it discovers it just fine, but when i try to hit OK, I get the error:
Unable to check out current file. The file may be read-only or locked, or you may need to check the file out manually.
I also tried adding a web reference under the "Advanced" tab, but there isnt any option to do so.
I tried doing so in a 7.1 targeted app, same error. My friend is doing this on a Visual Studio 2010, and he gets no such error.
