我的单元测试从 Visual Studio 2019 16.3.5 的 TestExplorer 中消失

测试引擎的输出是：

解决方案中的所有项目都在framework 4.8下构建都有Any Cpu 为Platform Target。不像32-bit prefer 选项处于活动状态。我选择了 x64 架构进行测试。没有使用 testFile 设置。

我尝试重建、清理重建、重新安装 VS，但没有任何效果。我不知道这个错误是什么。

【问题讨论】：

许多帖子都指向重新安装 .net framework 4.8 的解决方案。它对我不起作用。我回到了 16.2 版。该框架可以从这里下载。 docs.microsoft.com/en-us/visualstudio/releases/2019/history。仍在等待解决方案向前推进。正在调查中developercommunity.visualstudio.com/content/problem/594971/… 我也有同样的问题。我从 2017 年搬到了 2019 年，现在我突然不能使用 TestMethods 并且测试资源管理器是空的。这几天我一直在寻找解决方案。问题对我来说消失了。我的版本仍然是 16.2，我不知道发生了什么变化。我怀疑这是阻止服务启动的一些端口冲突。无论问题是什么，在它消失之前，它都能在降级和重启后幸存下来。刚升级到 VS 2019 后很快又回到了 VS 2017。看来 VS 2019 有很多奇怪的问题。 【参考方案1】：

Microsoft 发现了该问题，并在 VS 2019 16.5.2 版本中推出了修复程序。

现在可以使用VS 2019 16.5.2 Preview 2

【讨论】：

就我而言，只需更新到 16.4.5（当前版本）就足够了。这个错误已经存在并且可能由于多种原因而发生。检查其他帖子以获取可能的解决方案。请注意，一旦发生这种情况，您将不得不重新启动 VS。我导致某些进程崩溃。查找 Visual Studio 日志以了解有关崩溃的更多信息。 16.6.0 和重新启动 Visual Studio 并重新启动我的机器不工作 16.8.3，最新，每次重启VS时仍然弹出。 VS 2019 上的 16.10.3 仍在进行中。【参考方案2】：

我在 Visual Studio Enterprise 2019 版本 16.5.4 中遇到了这个问题，但重新启动 VS 解决了它。

【讨论】：

【参考方案3】：

我有一个类似的问题解决方法在运行窗口“devenv /ResetSettings”中尝试这个命令，它对我有用。

【讨论】：

【参考方案4】：

在以下版本中遇到此问题。清洁和重建解决方案对我有用。微软 Visual Studio 社区 2019 版本 16.6.3

【讨论】：

不幸的是，目前只有 Visual Studio 2019 社区预览版 v16.8.0 预览版 4.0 的解决方案重新启动 Visual Studio，清理和重建不起作用【参考方案5】：

通过关闭和打开 VS 修复。

一切正常（VS2019）并突然开始失败，并出现类似的（没有逐字比较）调用堆栈。重建没有帮助，从测试控制台手动杀死挂起的进程也没有帮助。重新打开VS后-一切恢复正常
