Windows.UI.ApplicationSettings.SettingsCommand

November 11, 2020 ยท View on GitHub

-description

Note

SettingsPane is deprecated, and might not work on all versions of Windows 10. Instead of using a SettingsPane, integrate settings options into the app experience. For more info, see Guidelines for app settings.

Creates a settings command object that represents a settings entry. This settings command can be appended to the ApplicationCommands vector.

-remarks

Note

This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX) and Using Windows Runtime objects in a multithreaded environment (.NET).

-examples

The following code shows how to add app commands by using the SettingsPane and SettingsCommand classes. For the full example, see App settings sample.
