Microsoft Codenames List

Daniel — Thu, 16 Dec 2010 17:24:00 +0000

Codenames are used to refer to products before their final release. Since many of these products, particularly new versions of Windows, are of major significance to the IT community, codenames are often widely used in discussions prior to the official release. Microsoft generally does not announce a final name until shortly before the product is finished, although it is usually possible to speculate (“Memphis”, for instance, was expected to be “Windows 97″, but was delayed).

Visual Studio / .NET build numbers explained

Daniel — Sun, 07 Jun 2009 06:39:01 +0000

Maybe you have been wondering why the build numbers of Visual Studio and .NET are always so high, for example 10.0.20506.01 for the recent Visual Studio 2010 beta. The reason for this is the format of the build number — it’s not an incrementing number as for Windows builds — the format of Visual Studio build numbers is YMMDD.NN.

Y: This increases every year the team is working on the product
MM: The month in which the build was compiled
DD: The day on which the build was compiled
NN: Number of recompiles of the build (during the development this number is mostly 00 or 01, but when a build gets branched for release, the other parts of the build number are freezed and only this part increments)

This build number format is not only used for Visual Studio and .NET, but also for many other products like Commerce Server 2009, Codename Geneva or Microsoft Silverlight.

Here are a few examples:

8.0.40607.16 – VS 2005 Beta 1 – 2004*, 7th June, recompile no. 16
8.0.50215.44 – VS 2005 Beta 2 – 2005, 15 February, recompile no. 44
8.0.50727.26 – VS 2005 RC – 2005, 27th July, recompile no. 26
8.0.50727.42 – VS 2005 RTM

9.0.20404.00 – VS 2008 Beta 1
9.0.20706.01 – VS 2008 Beta 2
9.0.21022.08 – VS 2008 RTM

10.0.11001.01 – VS 2010 CTP
10.0.20506.01 – VS 2010 Beta 1

*Orginally the Y was the last character of the calendar year, but with the beginning of the development of Visual Studio 2008 it has been changed to the number of the year the team is working on the project.
