To compliment the new Windows 10 Insider Preview (build 14388) released today, Microsoft has made a corresponding SDK pre-release available.
The Software Development Kit contains the tools developers need to produce universal applications for the latest build, with libraries, headers, and other resources.
Microsoft warns that this is not a full RTM release, despite what the EULA states, and does not have a “go-live” license. As such, any apps developed on the SDK will not go onto the Windows Store.
This build should only be installed on test machines and can not be used for applications that need store publication. With this release, Microsoft encourages developers to begin testing end to end with the new APIs provided.
Windows 10 Build 14388
The new SDK preview is based on Windows Insider Preview Build 14388, which added 44 fixes to the previous version. Microsoft listed the most important of these in their blog post:
We have updated the Store to version 11606.1001.39 with bug fixes.
We fixed an issue where Narrator keyboard shortcuts would not work after locking your PC and then logging back in and going to your desktop.
We fixed an issue where Narrator would not read the date and time under Settings > Time & language > Date & time.
We fixed a TPM driver crash that could result in the device bug-checking (bluescreen) and rebooting.
With the Windows 10 Anniversary Update only a few weeks away, now is a good time for developers to switch their update settings to include the latest Insider Preview builds. The latest SDK is available on the developer section on Windows Insider and can then be used to begin testing.
