This sample demonstrates how a Windows 10 app can use the ChatMesageManager.ShowComposeSmsMessageAsync API safely. By checking for the availability of transports we ensure ShowComposeSmsMessageAsync is only called if text message support is available on the current device. This means that the code also works great on desktop where SMS messaging is not available. More details can be found here: ChatMessageManager.ShowComposeSmsMessageAsync Crashes on Windows 10 Desktop
Unless otherwise noted, most of these code samples target Windows 10 and are universal. That is, they can be run on any device that runs Windows 10. To run these samples, you will need Visual Studio 2015 and the Windows 10 Software Development Kit (SDK). These can be found at http://developer.windows.com.
