Why are Visual Studio executables inside a folder named "Common7" instead of "Common10" or just "Common"?

Question

This is not the most important issue in the world, but I would like to know exactly why Common7 is named this way and does not increase with releases. Does this look like a problem with the version of Windows 7/8 (for example, Windows 8 - version 6.2)?

The folder in question (with VS2010) is usually located in:

%programfiles%\Microsoft Visual Studio 10.0\Common7\
or% programfiles(x86)%\Microsoft Visual Studio 10.0\Common7\

Answer 1

The first version of .NET Visual Studio was internal version 7.0, so I think they named the Common7 folder based on this. Then there were a lot of dependencies (possibly external, for example plugins or something else) that used the name Common7, so it would break too much if they changed it in a later version.

Answer 2

Too many add-ons and build scripts that have a hard-coded "Common7" folder name. In some ways, self-name is not so easy to find the correct path to the folder. The environment variable name is VS90COMNTOOLS for VS2008. Pay attention to the version number in the name, also not sure if it was available in VS2003.
