NTeam - Open-Source Project Offers Alternative to Visual Studio Team System
The project, known as NTeam, will use several existing open-source tools and applications, such as the NUnit and NAnt .Net unit testing and build tools, respectively, and will cover various stages of the application development life cycle, just like the upcoming VSTS does, said Jason Bentley, co-founder of the project, in Knoxville, Tenn.
