If you’re looking for TFS integration with Eclipse clients, there is currently one viable option and one to come: a commercial plug-in and an open source project with an anticipated tool.

• The commercial plug-in is called Teamprise and is quite mature. The Teamprise plug-in runs about $500 USD and scales nicely with more licenses. For example, 10 licenses go for about $2,300 USD.
• The VSTS Tools for Eclipse project aims to be an open source alternative; however, they admit they “have a long way to go before we have a working product.” Nevertheless, this promises to be a practicable solution eventually.
