Creating and registering custom DebugLaunchProvider

I am using Managed Package Framework (MPF) to create custom language service. I want to add few emulators/devices in "Start" Combobox.

After some research, I came to know that you need to extend an abstract class DebugLaunchProviderBase.

But now I am again stuck with how to register this class with visual studio, so it can list my targets.
