title: MvvmCross: Best way to raise event in ViewModel?
body: <p>I currently have a View (Android Fragment) and a coresponding ViewModel. I now want to raise an event in the ViewModel which the View can subscribe to.</p>
  
  <p>What's the best way to archive this? I heard a regular C# event (delegate) can lead to memory leaks? Is this the reason for the WeakSubscribe function? How to bind it to an event?</p>
