In my company we use Visual Studio 2008. Is VSS 2008 free?
First off, there is no VSS 2008. There is VSS 2005.
Second, it comes with certain versions of Visual Studio.
From this blog entry:
There is no VSS 2008
and
Q: Where do I get VSS2005 anyway?
A: If you have a Team Edition of Visual Studio 2005 or later, then VSS2005 is included in your license. It was included on the VSTS 2005 set of discs; you can also download it from MSDN. If you have a Professional Edition of Visual Studio or lower then you need to purchase VSS separately.
