public static PlayerSettings.WSAApplicationShowName tileShowName { get; set; }

In the Editor, Unity displays this as a list of checkboxes under Tile section in UWP Player Settings.

Note: If you do not set logo images for the corresponding tiles (medium, large, and wide), the platform ignores the tiles and does not display the application name. Additional Resources: mediumTileShowName, largeTileShowName, [[wideTileShowName.
