What is the new feature of Win10 system OneGet?

Last week, Microsoft pushed the Win10 preview version of Build9860, adding new features, such as local support for MKV format video, and so on, and a new package management framework, OneGet. Here is a introduction to the new Win10 system OneGet.

Accurately, OneGet is not new, it was first mentioned in April this year, but at that time it was an optional feature of the Win8.1 system, installed with the Windows Management Framework 5.0 preview. OneGet will now be installed on all Win10 systems, which means developers can take advantage of this feature to create new features.
Microsoft describes OneGet:
 OneGet is a new way to discover and install packages on the web. With OneGet you can do the following:
• Manage a range of packages , can be searched, obtained and installed.
• Search and filter in the software library and find the software you need
• Seamlessly install and uninstall one or more software using a single PowerShell command line.
If you are not familiar with package management, But for developers, it's a useful tool for uninstalling, upgrading, or installing native apps. At present, OneGet is still an early version, and it is not clear which Win10 version Microsoft will launch.
