Handling simultaneous service requests

We may require a single service to be able to handle multiple requests from multiple sources simultaneously.

How to do it...

If we want a service to be able to handle multiple requests simultaneously, we inherit from the Service type, which provides the required features:

1. We first need a type that inherits from Service:

   [Service]
   public class XamarinService : Service {
     public override StartCommandResult OnStartCommand(
       Intent intent, StartCommandFlags flags, int startId) {
       return StartCommandResult.Sticky;
     }
     public override IBinder OnBind(Intent intent) {
       return null;
     }
   }

2. Now, we can create a method that handles multiple requests:

   private int started = 0; private async void ProcessRequest() { started++; await Task.Run ...
