Developing native C# applications for Windows 10 Universal Windows Platform and Windows 8 Universal
To develop a native C# application for Windows 10 Universal Windows Platform (UWP) and Windows 8 Universal, you must create a Visual Studio project and then add the IBM MobileFirst™ Platform Foundation SDK files to it.
When you create native API applications, you can choose to create a Windows 8 Universal environment that supports either desktops and tablets or phones or a Windows 10 UWP environment. The contents of the associated application descriptor file reflect your choice.
