 <sub> ** Some platforms support launching your application when the user clicked a notification. The associated action identifier is passed as a command-line argument. </sub>
 
+# Application Context
+
+Most operating systems require you to register the application in some form before you can actually send notifications. This registration process is handled by the `ApplicationContext`. On Windows (see `WindowsApplicationContext`) it will create and assign a [Application User Model Id](https://docs.microsoft.com/en-us/windows/win32/shell/appids) to the current process and associate a shell link in the start menu with it. This will cause your application to appear in the Windows Start Menu.  On Linux/FreeDesktop.DBUS, the application context is just holding the name and optional icon of your application.

 # Avalonia
 
 The `DesktopNotifications.Avalonia` package offers support for the [Avalonia](https://github.com/AvaloniaUI/Avalonia) project. It doesn't do much on its own, it just provides helpers to register
 the `INotificationManager` with the application builder. You can see an example of it in the Example.Avalonia project.

 # Help wanted
 
 My MacBook Pro is 11 years old now and it does not run OSX Mojave or higher. Unfortunately, Apple deprecated `NSUserNotificationCenter` with OSX 10.14 and I suppose they want us to use the newer `UNUserNotificationCenter` API instead. I would kindly appreciate any contributions from folks that own a more modern Mac and are interested in implementing the OSX backend using the new API.
