说明:

1. MSDN Premium subscriptions 有5个等级，Team Suite, Software Architects ,Software Developers,Software Testers ,Professional Developers

2. Visual Studio 2005 Team Foundation Server 需要有单独的License ，和微软其他服务器产品的模式一致，这意味着每个安装需要一个服务器的License，另外每个存取/访问Team Foundation Server的客户端也需要一个CAL(Client Access License)，而且Visual Studio 2005 Team Foundation Server包含一个SQL Server 2005标准版的License。还涉及Visual Studio 2005 Team Foundation Server 和Office System、Windows Server 2003和Windows SharePoint Services的License。详细信息可以看这里

3. Visual Studio 2005 Team Suite 也依然是一个Team Foundation Server 的客户端，并不包含Team Foundation Server ，但包含一个访问Team Foundation Server 的CAL，另一方面说它功能最全，是指它覆盖了Team Edition for Software Architects, Team Edition for Software Developers, Team Edition for Software Testers 三个版本的所有功能。

4. Visual Studio 2005 Team Foundation Server还有一个 Workgroup Edition 版本，这个包含在Visual Studio 2005的Team Suite,Team Edition for Software Architects, Team Edition for Software Developers, Team Edition for Software Testers 版本中，而且功能和Team Foundation Server 同样，但是它功能受限，只能包含5个帐号。License上，它不需要一个Team Foundation Server的License，但需要一个MSDN Premium 订阅的License，使用上则遵从MSDN Premium 订阅的License。

5. Visual Studio Standard Edition 和Visual Studio Professional Edition 你可以认为它是传统意义上的Visual Stuido 2005，也就是Visual Studio 2005 Team System没有出现前的Visual Studio比较相似的版本，和Visual Studio 2005 Team 客户端系列(Team Suite,Team Edition for Software Architects, Team Edition for Software Developers, Team Edition for Software Testers)的版本相比，这两个工具没有Itanium 64的编译支持，只有x64的编译能力，另外最大的缺陷是这两个版本不能连接Visual Studio 2005 Team Foundation Server，而且没有Visual Studio 2005 Team 客户端系列所有的Code Profiling,Static Analysis,Code Coverage,Test Case Management等功能，只能连接Visual SourceSafe 的源代码服务器。简单的说，如果你的工作和Visual Studio 2005 Team System没有什么关系，那么你可以考虑使用Visual Studio Standard/Professional 版本。

注：本人使用Visual Studio2005 Professional Edition 安装了Team Foundation Server 的团队资源管理器，可以使用Foudation Server的源代码管理工具！
