If there are APIs in the supported list that appear greyed out or disabled in Visual Studio, you can make a small change to your source file, to access them. Several new APIs were added to the Supported APIs list in the App Certification Kit and Windows Store. Legacy behavior is available when linking with legacy_stdio_float_rounding.obj. To access the Windows 10 WinRT API Pack, see the nuget package. If you would like to use the ENUM tagServerSelection, you will need to include wuapi.h or wuapi.idl.
Apps that were linking against irprops.lib can switch to bthprops.lib as a drop-in replacement. Apps that were linking against api-ms-win-net-isolation-l1-1-0.lib can switch t OneCoreUAP.lib as a replacement.
