I'm using Visual Studio to load the webservice, but when using WCF in VS itself does not work. Generating in WebReference works perfectly, but does not generate the Begin and End methods if I use the generator WCF Silverlight have the same problem. Do not have the Begin and End methods and not using the Async feature.
Please Xamarin and staff, fix these problems and make the plugin more complete and correct. To avoid having to stay open Xamarin Studio, XCode, InterfaceBuilder, Visual Studio to program for ios.
