Microsoft is releasing a new Windows 10 Preview Build of the SDK. These builds are to be used in conjunction with Windows 10 Insider Preview Build 17120 or greater.
The Preview SDK Build 17120 contains bug fixes and under development changes to the API surface area.
Things to note:
- This build works in conjunction with previously released SDKs and Visual Studio 2017. You can install this SDK and still also continue to submit your apps that target Windows 10 Creators build or earlier to the store.
- The Windows SDK will now formally only be supported by Visual Studio 2017 and greater. You can download the Visual Studio 2017 here.
- This build of the Windows SDK will install on Windows 10 Insider Preview and supported Windows operating systems.
- C++/WinRT Now Available: The C++/WinRT headers and cppwinrt compiler (cppwinrt.exe) are now included in the Windows SDK. The compiler comes in handy if you need to consume a third-party WinRT component or if you need to author your own WinRT components with C++/WinRT. The easiest way to get working with it after installing the Windows Insider Preview SDK is to start the Visual Studio Developer Command Prompt and run the compiler in that environment. Authoring support is currently experimental and subject to change. Stay tuned as we will publish more detailed instructions on how to use the compiler in the coming week.
- New MIDL key words.
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:
If any of these keywords is used as an identifier, it will generate a build failure indicating a syntax error.
