Solution that demonstrates problem

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:
Gecko/20101026 Firefox/3.6.12

When inheriting from Android.App.IntentService, an
System.InvalidOperationException is thrown with message: The type '[TypeName]'
needs to have a public default constructor.

Intellisense in Visual Studio correctly detects the available constructors:
IntentService(string name)
IntentService(IntPtr handle)

The error occurs when the project is built.

Reproducible: Always

Steps to Reproduce:
1. Create a new MonoDroid Application
2. Add a new class and inherit from IntentService
3. Build project
Actual Results:  
Error    1    System.InvalidOperationException: The type
'IntentServiceSandbox.MyIntentService' needs to have a public default
constructor.    C:\Users\Dan\Documents\Visual Studio

Expected Results:  
Successful compilation
