I am making a portable C# class library and I am trying to add a web service reference to my project.

I was having the same problem. Right after creation of a new project of type "Blank App (Xamarin.Forms Shared) in Visual Studio there was no "Add Service Reference" link when I right clicked on PCL. What I did was I just created another PCL and referenced it instead of default one (which I deleted later). I chose project of type "Class Library (Portable for iOS, Android and Windows)".
And then I went to project's properties and unselected "Windows Phone 8.1" checkbox.
And "Add Service Reference" link appeared all over the sudden.
I am using Visual Stuido 2015 Community Edition (version 14.0.25123.00 Update 2). Hope this will work for you guys too.
