c# - Visual Studio 2017 在调试期间出现异常后需要重新启动

Question

我在 Visual Studio 2017(版本 15.7.1)中遇到一个奇怪的问题。在调试 session 期间发生异常后，Visual Studio 无法生成。这是在使用 net462 的 WebApi 项目中发生的。正在使用的库之一是在 .NET 4.6.2 中构建的自定义库，它使用 Entity Framework 6、Automapper 和 LinqKit。

出现异常后，如果我尝试构建，则会出现以下构建错误，我必须重新启动 Visual Studio 才能成功构建:

1>Build FAILED.

我在网上搜索过，但我找不到任何相关的内容。我什至向微软开了一张求助票，但他们希望我给他们一个重现问题的小项目。我无法在我们的专有代码之外重现该问题，因此我无法向他们发送任何内容。但是，我可以补充一点，如果我从组合中删除 .NET 4.6.2 项目，则不会发生这种情况。由于这不是对我们的生产代码的现实期望，我正在寻找问题的解决方案。

这不会发生在我团队中的每个人身上，只会发生在我的电脑上。

这是我尝试过的:

• 删除 bin 和 obj 文件夹 - 在出现异常后这是不可能的，因为 Visual Studio 已锁定这些文件夹中的文件。可以在重启之后和调试 session 之前删除它们
• 安装最新的 Visual Studio 更新 (15.7.1)
• 在调试期间禁用诊断工具
• 在构建和调试期间禁用实时单元测试

我很迷茫。发生异常后如何让 Visual Studio 恢复构建？还有其他人看到过类似的行为吗？

谢谢

Answer 1

在多次尝试解决此问题后，我最终决定卸载并重新安装 Visual Studio。这解决了这个问题。我没有重新安装所有第三方插件 (Resharper)，所以我不确定是否是其中一个原因造成的。

问题消失了。我现在可以在调试 session 期间出现异常后重建。
