The TFS Integration Platform is a project developed by the Team Foundation Server (TFS) product group and the Visual Studio ALM Rangers to facilitate the development of tools that integrate TFS with other systems. Currently, the scope of this project is to enable TFS to integrate with other version control and work-item/bug tracking systems, but the eventual goal of this project is to enable integration with a broader range of tools/systems (i.e. build). This platform enables the development of two major classifications of tools: tools that move data unidirectionally into TFS, and tools that synchronize data bidirectionally.
Prior to this project, we had a similar effort called the TFS Migration and Synchronization Toolkit. This platform is designed to replace that project.
