Virtual Developer Workshop: Containerized Development with Docker
Windows 8 is designed to be different than previous versions of Windows in a similar fashion to how Windows 95 was different than Windows for Workgroups--it's an effort by Microsoft to reinvent the Windows operating system. Although Microsoft is touting Windows 8 as a "one size fits all" OS, in reality the two parts that it is made of are not just different "editions" but rather, they are very different animals.
To some developers, Windows 8 looks like the Frankenstein monster of operating systems, with part of the monster being made of Win32/Desktop, and the other half made of WinRT/Metro. If the two parts are able to work together, with the whole being superior to the individual parts, that will be great, but what if instead, each part works against the other?
