Description of Problem:
Monodroid application quits in emulator without even showing "Force Close"
window when making call to Web Service while ProgressDialog is shown.

Steps to reproduce the problem:
1. In VS 2010 right-click Service References->Add Service
Reference->Advanced->Add Web Reference 

http://soatest.parasoft.com/calculator.wsdl

2. Write following code

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            var p = ProgressDialog.Show(this, "Calculating", "Please wait");
            float result = 0;
            try
            {
                com.parasoft.soatest.Calculator ws = new
com.parasoft.soatest.Calculator();
                result = ws.add(5, 3);
            }
            catch (Exception ex)
            {
                Toast.MakeText(this, "Exception: " + ex.Message,
Toast.LengthLong).Show();
            }

            p.Hide();
            Toast.MakeText(this, "Result: " + result.ToString(),
Toast.LengthLong).Show();

        }

Actual Results:
App crashes in emulator without Force Close.


Expected Results:
Toast saying "Result: 8" or "Exception: xxxx".

How often does this happen? 
Always
