I'm trying to connect from Xamarin to a web service and for this reason I downloaded your example called Call a REST Web Service but it doesn't works correctly. Doesn't appears nothing when I run the application. The following image shows the error that appears when I'm debugging it.
I would like to know the steps about how to set a connection with a web service. I know that there is a lot ways to do it. I'm interested in the way easier to get it.
