随着 SSDT 15.7.1 的发布，Team Explorer 不再显示为 SSDT 中现有的 Visual Studio 安装实例选项.起初我担心 SSDT 安装会安装一个没有 TFS 连接的 Visual Studio shell，但事实并非如此.似乎 Visual Studio shell 的 SSDT 安装基于 Visual Studio Team Explorer 2017 已经安装在机器上并且 SSDT Visual Studio shell 实例具有完整的 TFS 连接这一事实！

With the release of SSDT 15.7.1, Team Explorer no longer shows up as an existing Visual Studio install instance option within SSDT. At first I was concerned that the SSDT install would install a Visual Studio shell with no TFS connectivity, however this was not the case. It appears that the SSDT install of the Visual Studio shell picks up on the fact that Visual Studio Team Explorer 2017 is already installed on the machine and the SSDT Visual Studio shell instance has full TFS Connectivity!
