here simple code snippet use guide:

//first @ class level, create private variable client. private service1client _client; private button _addbuton; private textview _txtdeptname;  //initialize _client in oncreate() method. protected override void oncreate(bundle bundle) {      base.oncreate(bundle);       var endpoint = new endpointaddress("http://<ipaddress:port>/service1.svc");       var binding = new basichttpbinding{         name = "basichttpbinding",         maxbuffersize = 2147483647,         maxreceivedmessagesize = 2147483647     };      timespan timeout = new timespan(0, 0, 30);     binding.sendtimeout = timeout;     binding.opentimeout = timeout;     binding.receivetimeout = timeout;      _client = new service1client(binding, endpoint);     _client.adddeptcompleted += clientadddeptcompleted;      _addbutton = findviewbyid<button>(android.resources.id.add);     _addbutton.click += addbutton_clicked;      _txtdeptname = findviewbyid<textview>(android.resources.id.name); }  //then within event handlers, public void addbutton_clicked(object sender, eventargs e) {      _client.adddeptasync(_txtdeptname.text); }  //handle request completed event. private void clientadddeptcompleted(object sender, adddeptcompletedeventargs adddeptcompletedeventargs) {      //todo: notification request has completed. } 

you should able follow similar pattern other buttons , service calls well. apologize if have made typos. i'm going bit of memory , of wcf instructions on xamarin site.
