Xamarin PCL Web Service Connection

pleachim@outlook.com

Hi,
I hope I can find someone who already tried to connect to NAV Web Service from am Xamarin.Forms Project inside the PCL and is willing to share his knowledge.

I have trouble to connect to a simple Codeunit which has only one function with two parameters.

I need to get the _Out Parameter back in a synchronous call. There is a way to add a Service Reference if you don't develop for Windows Phone 8. But even then I can't call my web service.
