API Sets for Universal Windows Platform (UWP) apps
API Sets available in Windows 10.
API Sets available to Windows 10 apps
A Universal Windows Platform (UWP) app, or Windows Runtime Component, written in C++/CX has access to the Win32 APIs that are part of the Universal Windows Platform (UWP). These Win32 APIs are implemented by all Windows 10 device families. For convenience, the "umbrella" library WindowsApp.lib is provided in the Microsoft Windows Software Development Kit (SDK) and it provides the exports for the API surface defined in API Sets plus additional APIs that are contained in well-layered system DLLs. This topic lists all the APIs in WindowsApp.lib. Link your app with WindowsApp.lib to access these APIs. Linking to WindowsApp.lib will add to your app dependencies on dlls that are present on all Windows 10 device families.
A classic Desktop app has access to even more Win32 APIs, and these are also accessible by linking to WindowsApp.lib.
Also see Dlls for UWP apps, and Win32 and COM for Windows Runtime apps and UWP apps.
