Web service not getting called and crashing

I am new to MonoDroid, I have developed an application on MonoTouch which uses web-services and i'm trying to port it on Android. I am using MonoDevelop on a Mac ( Mac OS X ).

I've tried to run the "Consuming Web Services" tutorial from Xamarin ( http://android.xamarin.com/index.php?title=Documentation/Guides/Consuming_Web_Services&file=58 ) but it doesn't work, neither on my 2.2 simulator, nor on my HTC Legend device.

When i click on the button, the application freeze for 3-4 seconds, I don't see any network activity on the status bar and then it crashes and cl开发者_Go百科ose application.

Here's the console trace :

Apparently it was coming from the fact that I was using WCF implementation of web services when i had to use .NET 2.0.
