Yesterday Microsoft
released Windows 10 SDK Preview Build 17046 to developers. This SDK can be used with
Windows 10 Insider Build 17040 or later. This SDK build includes C++/WinRT headers and cppwinrt compiler (cppwinrt.exe) which will help developers when they want to use a third-party WinRT component or if they need to write their own WinRT components with C++/WinRT. This SDK build also contains bug fixes and underdevelopment changes to the API surface area.
You can read about the API changes
here.
Known Issues:
■ “All tests run with Windows App Certification Kit will fail. During installation, please uncheck Windows App, Certification Kit”
■ Installation on an operating system that is not a Windows 10 Insider Preview build is not supported and may fail.
Breaking Changes:
♦ New MIDL keywords: As a part of the “modernizing IDL” effort, several new keywords are added to the midlrt tool. These new keywords will cause build breaks if they are encountered in IDL files. The new keywords are:
■ event
■ set
■ get
■ partial
■ unsealed
■ overridable
■ protected
■ importwinmd
