How do the .NET Framework, CLR and Visual Studio version numbers relate to each other?

With the recent announcement of .NET 4.0 and Visual Studio 2010, it is becoming ever more difficult to keep track of what .NET Framework versions build on what version of the CLR and belong with which version(s) of Visual Studio.

Is there a definitive table that shows these relationships?

Visual Studio                                 CLR           .NET Framework

Visual Studio .NET (Ranier) 1.0.3705 1.0 Visual Studio 2003 (Everett) 1.1.4322 1.1 Visual Studio 2005 (Whidbey) 2.0.50727 2.0 Visual Studio 2005 with .NET 3.0 Extensions 2.0.50727 2.0, 3.0 Visual Studio 2008 (Orcas) 2.0.50727 2.0 SP1, 3.0 SP1, 3.5 Visual Studio 2008 SP1 2.0.50727 2.0 SP2, 3.0 SP2, 3.5 SP1 Visual Studio 2010 (Hawaii) 4.0.30319 4.0

Expanding on this a bit, and including some of the information from dok1's answer, the actual version numbers for the different shipped builds of the .NET Framework are available on Aaron Stebner's blog, which covers everything from 1.0 through 3.5 SP1.

The actual Visual Studio version numbers are:

Product Name                                 Version              Ship Date

Visual Studio .NET 7.0.?? 02/2002 Visual Studio .NET 2002 Service Pack 1 7.0.?? Visual Studio 2003 7.1.?? 04/2003 Visual Studio 2003 Service Pack 1 7.1.6030 09/13/2006 Visual Studio 2005 8.0.5072.42 Visual Studio 2005 Service Pack 1 12/14/2006 Visual Studio 2008 9.0.21022.8 11/19/2007 Visual Studio 2008 SP1 9.0.30729.1 Visual Studio 2010 10.0.30319.1 04/12/2010 Visual Studio 2010 SP1 10.0.40219.1 03/03/2011

Please help fill in the missing pieces. This is all I could easily find online.

Thanks to @DannySmurf for the information on the full version numbers for the CLR.

Note that while 3.0 bascially only added new assemblies (same CLR), 3.5 added new assemblies, new compiler, and updated the CLR to SP1 level.

Framework 4.0 will be a whole new CLR (4.0, no CLR 3.x) which will run side-by-side with CLRs 1.1 and 2.0. It will also have all-new assemblies versioned 4.0 instead of using the 2.0 assemblies.

(This was collected from various answers and linked documents, especially the MSDN article How to determine which versions and service pack levels of the Microsoft .NET Framework are installed linked by DOK.) A full list with KB update versions and support retirement dates can be found on Wikipedia, List of .NET Framework versions.

It's hard to find, isn't it? I believe these are the versions (ignoring service packs)

• Visual Studio version 6 = last one before .NET, released in 1998
• Visual Studio 2002 = version 7.1, Rainier, first .NET version retroactively added 2002 to the name, .NET 1.0 -- released Feb 2002
• Visual Studio 2003 = version 7, Everett, .NET 1.1 -- released early 2003.
• Visual Studio 2005 = version 8 Whidbey, .NET 2.0 & 3.0 -- launch was Nov 2005. No longer called Visual Studio .NET
• Visual Studio 2008 = version 9 Orcas, .NET 3.5 -- released 11/19/2007 as 9.0.21022.8
• Visual Studio 2010 = version 10 Hawaii

The next version of Visual Studio Team System is Rosario.

How to determine which versions and service pack levels of the Microsoft .NET Framework are installed will give you more information about build numbers and service packs, but only through .NET 2.0.
