How can I debug Custom Code in Visual Studio?

I would like to debug the code that I have written in HL7Spy. How do I do this?

If you have Visual Studio installed, you can add Break(); to the OnStart() method of your custom code to trigger the Visual Studio debugger to launch when you push the “Run” button in the user interface.

  public override void OnStart()

Once you are in Visual Studio you can set break-points, watch variables, etc.
