Project must be deployed before it can be started

I'm using Visual Studio 2013 and I'm trying to run the Xamarin store app for the Android project side and I receive the message:

The project XamarinStore.Droid needs to be deployed before it can be started.
Verify the project is select to be deployed in the Solution Configuration Manager.

I'm using the Xamarin Android Player for an emulator. Is this the recommended practice? All examples I see always shows "Mixed Platforms" when debugging.
