AddInController aiCtrl = AddInController.GetAddInController(CalcAddIn);
AppDomain AddInAppDom = aiCtrl.AppDomain;

// Activate another add-in in the same application domain.
Calculator CalcAddIn3 =

// Show that CalcAddIn3 was loaded
// into CalcAddIn's application domain.
AddInController aic = AddInController.GetAddInController(CalcAddIn3);
Console.WriteLine("Add-in loaded into existing application domain: {0}",
