错误CS0234：名称空间'Microsoft'中不存在类型或命名空间名称'VisualStudio'（您是否缺少程序集引用？

我正在使用Visual Studio 2015专业版在我的本地计算机上运行一些测试用例 . 我能够在本地构建解决方案并运行测试用例 .

当我在TeamCity服务器上构建我的应用程序（构建代理也托管在团队城市服务器上）时，我收到以下错误：

我正在使用以下nuget包：

我的团队城市服务器盒上安装了.net framework 4.0 . I am trying to avoid installing Visual Studio on team city server,

这个错误的原因是什么？
