@p0ke thanks for finding a solution! I'm in the process of integrating LED number control within the client application.
For the rest if you are having issues with icons after Xamarin update: do not update GTK Sharp with Xamarin. You can update Xamarin, but leave GTK Sharp old version. Simple way to fix this:
- Close Xamarin and BlinkStick Client
- Open up Programs and Features in the control panel, uninstall Gtk# for .NET 2.12.x
- Reinstall BlinkStick Client application
Now you can use both Client application and Xamarin, but do not upgrade Gtk# when Xamarin suggests you to do that. For some reason new version of Gtk# removed stock icons and they are no longer available in the default installation. I will have to add them manually into the next Client application release.
