【问题描述】：
我正在使用 Manjaro linux 并尝试调试默认的 ASP.NET Core MVC 项目，但调试停止，没有任何错误
我在Meow 文件夹中使用dotnet new mvc 创建了项目，没什么特别的，然后添加了一个新配置.NET Core Launch (web)。
事实证明，在tasks.json 中定义的build 任务中只调用了dotnet build，正如在launch.json 的preLaunchTask 中定义的那样，这就是调试过程开始和停止而没有显示任何错误。
运行 dotnet run 时，一切正常，所以我怀疑问题更多来自我的 Visual Studio 调试配置。
在终端标签中我有：

下面两个自动生成的文件看起来不错。

尝试卸载omnisharp并重新安装（中间有VSCode重启）：

【问题讨论】：
-
您确定 C# 扩展已正确安装 .NET Core 调试器吗？
-
@LexLi 我认为是这样（Omnisharp 选项卡在启动和检查项目时没有显示任何错误）。此外，调试一个简单的控制台应用程序似乎也无缘无故停止了。
-
重新安装扩展，它应该尝试再次下载调试器。确保网络允许外部下载。
-
@LexLi 我更新了我的帖子，显示了 Omnisharp 日志。调试器已经设置好了。
-
Microsoft .NET Core 调试器不是开源的，它对 Linux 发行版的支持应该非常有限。我不认为 OmniSharp 的人可以在这方面提供帮助，但您可能会看到他们所说的。
