问题
Is it possible to add a web reference to my project in Visual Studio 2012? In Visual Studio 2010 it was possible by clicking the "Advanced" button in the "Add Service Reference" dialog, as it is written on this page :
Add Web Reference in Visual Studio 2010
But in Visual Studio 2012 there is no section "Compatibility" in the "Service Reference Settings" and no "Add Web Reference" button in this dialog. I want to use SOAP web-service, but it works correctly only when I add it as Web Reference (in .NET Framework 2.0 compatibility mode. If I Add it as usual service reference I have an exception during using this service).
How to add old-style web reference to my project?
Or how to use my web service with new style of service references?
Thanks

Visual Studios 2013 uses newer version of .NET Framework 4.5.1, which will not work with this web service http://wsf.cdyne.com/weatherws/weather.asmx and others. but using .NET 3.5 works!
so, if your starting a new project select from drop down menu .NET Framework 3.5 or if you are already in a project and want to change Framework
1 Click [DEBUG] > '<YOUR_PROJECT_NAME>' Properties
2 Click [Build] and change target Framework
3 Click [OK]
