我正在进行从 TFS2010 到 TFS2012 的测试升级。他们正在使用升级模板来运行大量自定义 MSBuild 任务，以自动化他们的构建和部署。MSBuild 项目最初是为 TFS2005 创建的，并在某些时候直接升级到 TFS2010。他们正在构建的解决方案主要针对 .NET 2.0，并且他们仍在使用 VS2005 进行大多数开发。
到目前为止，我已经安装了带有 Update 1 的 VS2005、VS2010 和 TFS2012（按此顺序），并将它们的 TFS2010 数据库升级到 TFS2012。构建控制器与应用层和数据库位于同一台机器上，只是因为这是一个“概念证明”升级，以识别在真正升级之前需要在构建过程中解决的任何问题。
当我运行他们的任何基于 MSBuild 的构建时，我收到以下错误：
C:\Builds\18\Web\ES-INTEGRATION-WebTest\BuildType\TFSBuild.proj (75)：必须配置“Microsoft.TeamFoundation.Build.Client.IBuildDetail”类型的扩展才能运行此工作流。C:\Builds\18\Web\ES-INTEGRATION-WebTest\BuildType\TFSBuild.proj (75)：“获取”任务意外失败。
