C# Can't generate task based operations using service reference

Question

When I'm adding a service reference in Visual Studio Express 2012 for Windows Phone I can't choose the option "generate task based operations". I can't even uncheck the Allow generation of asynchronous operations checkbox.

I'm using the following address: http://www.webservicex.com/globalweather.asmx?wsdl

I'm missing something?

Answer 1

It seems that this option is disabled for WP8 projects.
