团队生成（XAML）失败，错误为TF215097

正常运行数周后，TFS 2015 XAML生成突然失败，出现错误TF215097

构建定义本身和使用的构建活动在此期间没有改变

---

环境正在运行VisualStudio 2015更新1，Team Foundation Server 2015更新1在Windows Server 2012R2../P>< P>中，结果发现这个错误是由于安装了一些通过Windows Update传递的热修复程序。报告准确地解释了根本原因是什么

卸载和重新启动服务器解决了此问题。重新启动后，修补程序会自动重新应用，而不会重新出现问题

感谢我的验证：）
