Note Note that this class and its methods are supported for the maintenance of legacy desktop apps that used it in earlier versions of Windows; and if you do use this class, you must specify the Windows.Devices.Sms.LegacySmsApiContract in your app's manifest. Do not use this class if you are developing new apps for Windows 10. Instead, use the members of this namespace that do not require the Windows.Devices.Sms.LegacySmsApiContract.
