Windows 10 Preview build 16278 SDK now available for developers

A new preview build of the Windows 10 SDK is now available for developers with API updates and more. This SDK preview release is labeled build 16278, and corresponds with the release of Windows 10 Insider Preview build 16278 last week. The Mobile emulator for build 15240 is also now available.

Here's a look at the known issues with this release:

Known Issues

  • Compilation fails on non-Windows 10 platforms When building apps with the minimum target platform version set to 10.0.16278.0 you get the build error: "The program can't start because api-ms-win-eventing-classicprovider-l1-1-0.dll is missing from your computer. Try reinstalling the program to fix the problem." This will occur if the minimum target platform version is set to 10.0.16278.0. To work around this, edit your project file and change the version to a previous released SDK.

Breaking Changes

  • ecmangen.exe removal from the SDK: Ecmangen.exe will no longer ship with the Windows SDK. Developers who rely on ecmangen for event manifest creation are advised to install the Windows Creators Edition of the SDK to obtain the file. Developers may also use notepad or other XML editor of choice for manifest creation. A schema file is available on MSDN to aid in manifest creation, for tools that support it.

The list of changes and known issues in this release is short, as is to be expected this late in development. Still, you can get a full look at the API additions and removals with the full release notes at Microsoft. You can get your hands on the new SDK directly from Microsoft as well.

Updated September 5, 2017: Microsoft has also pushed out Windows Server Insider Preview Build 16278 for testers. You can find the full release notes at the Windows Blog now.
