'''''Longhorn''''' was the codename for the planned successor of [[Windows XP]]. The project was reset and replaced with a new project - ''Longhorn Omega-13'' which was later renamed [[Windows Vista]]. Early builds of Windows Vista were often referred to as "Longhorn", causing confusion.
'''''Longhorn''''' was the codename for the planned successor of [[Windows XP]].


One of the original - and largest - changes is that, with "Longhorn", the .NET Framework would be integrated into the core Windows platform, deprecating the traditional Win32 API. During development, portions of the operating system were rewritten, causing memory leaks and instability, particularly in [[Windows Explorer]].

Contrary to popular belief, most of the early builds of "Longhorn" are not based on Windows XP, but [[Windows Server 2003]] (Build 3663) Release Candidate code.
Development was reset, but post-reset builds continued to use the "Longhorn" codename until the final name, [[Windows Vista]], was announced on 22 July 2005.

Longhorn was the codename for the planned successor of Windows XP.

One of the original - and largest - changes is that, with "Longhorn", the .NET Framework would be integrated into the core Windows platform, deprecating the traditional Win32 API. During development, portions of the operating system were rewritten, causing memory leaks and instability, particularly in Windows Explorer.

Development was reset, but post-reset builds continued to use the "Longhorn" codename until the final name, Windows Vista, was announced on 22 July 2005.

History

Codename

"Longhorn" was chosen as the codename for the operating system to represent its initial status as an internim release between Windows XP (codenamed "Whistler") and "Blackcomb". Whistler and Blackcomb are names of mountains in British Columbia, Canada,[1][2] and Longhorn is the name of a saloon located in between the two mountains, representing the operating system's initial status as an internim release between the two products.[3] Bill Gates would later state that this choice for a codename of the operating system was "a bit random".[4]

Codebase

The popular belief is that pre-reset "Longhorn" builds are based on Windows XP. This was likely spurred by Paul Thurrott's statement on his review of build 5048: "The problem, I was told recently, was that the underpinnings of Longhorn--then based on the Windows XP code base--were struggling under the weight of all of the technologies that Microsoft planed to implement in this release."[5] However, pre-reset "Longhorn" builds are based, not on XP, but on Windows Server 2003 release candidate code. The xpclient release branch, dedicated to XP, spun off from the main branch in 2001. The main branch continued to compile Server 2003 builds at the 3xxx range, such as build 3663 (release candidate 1), until the dnsrv branch dedicated to Server 2003 spun off from the main branch in 2002. After that, the main branch began compiling Longhorn builds.[6]
