Windows 10 SDK Preview Build 17040 now available

SDK

Microsoft is releasing a new Windows 10 Preview Build of the SDK (17040). These builds are to be used in conjunction with Windows 10 Insider Preview Build 17040 or greater.

The Preview SDK Build 17040 contains includes C++/WinRT headers and cppwinrt compiler (cppwinrt.exe) , bug fixes and underdevelopment 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.

What’s New:

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.

What’s New:

  • 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

Breaking Changes

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:

  • event
  • set
  • get
  • partial
  • unsealed
  • overridable
  • protected
  • importwinmd
