Developers working alone, or on a small team can enjoy the improvements made to
Visual SourceSafe 2005. Along with rich integration with the Visual Studio 2005 IDE, remote access over HTTP, performance and stability improvements, and Unicode support are all part of Visual SourceSafe 2005. With these key additions and improvements, Visual SourceSafe 2005 continues to be an excellent option for developers looking for a cost-effective, desktop-based source control solution.
For those developers who are looking for a complete collaboration platform,
Team Foundation Server is the best option. Team Foundation Server is the foundation for the newly introduced Visual Studio 2005 Team System - a fully integrated, software development lifecycle tool. Team Foundation Server provides a robust source control system, integrated work items, and dynamic reports, all built on SQL Server 2005. When combined with Visual Studio Team System, everyone that is part of a software project - architects, project managers, testers, and developers - can be part of an integrated, productive environment that helps tame the most challenging of projects.
