If you are a Windows Phone app developer, you can check out the features of a more recent version of Windows 10 for phone via the emulator included in the latest Visual Studio tools release.



Form Windows Central:

Keep in mind that this emulator is designed to be used just by app developers. If you are a regular Windows Phone consumer, we highly recommend that you don't download the Visual Studio tools just to check out the features in this build, as it will almost certainly be full of bugs and performance issues. Microsoft is expected to release a new Windows 10 for phone build to Windows Insider members sometime early next week, after missing a previously announced deadline for the end of April. The new build should also have support for the new universal Office apps for phones.
