A team of developers has started a project to create an open-source alternative to Microsoft's 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. NTeam, chiefly, will tie all open-source components as well as commercial software together, Bentley said.
