Question

每次尝试打开新的SQL Server Management Studio查询窗口时，我都会看到此异常，或者右键单击任何用户对象以修改，查看或生成脚本：

无法加载文件或程序集System.Threading.Tasks.Dataflow， Version = 4.5.24.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39;要么其中一个依赖项。该系统找不到指定的文件。（Microsoft.VisualStudio.ExtensibilityHosting）

我已经卸载并重新安装了SSME 2017.3，甚至升级到SQL Server 2017 Developer Edition都是为了解决这个错误，没有一个工作。

例外情况如下：

===================================

Could not load file or assembly 'System.Threading.Tasks.Dataflow, Version=4.5.24.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. (Microsoft.VisualStudio.ExtensibilityHosting)
