Problems adding a service reference to a WP8 app

问题

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.

Follow these step, hope it will work:

1. Go to Debug → Options.
2. Select Source Control in the list.
3. Under Current Source ControlPlug-in drop down select none.

OK, I found a solution: run Visual Studio as Administrator.

I had the similar issue with Updating Service reference.

My solution was :

• Right click on the Service reference
• Check Out for edit
• Then try to update the reference.

I had the same problem and none of the suggested tricks worked, but when I opened the Advanced dialog and selected Add Web Reference all went well.
