|
// shockingly it may be the best approach, at least in the non-installed case.

// The proper Windows APIs for this require WinRT (ie C++/ a DLL), and also require
|
|
// the app to be installed with a unique ID in the start menu, and to pass this ID
|
|
// when sending the notification. This could be a future exploration for the installer.
