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，但调试停止而没有任何错误

I am using Manjaro linux and tried to debug the default ASP.NET Core MVC project but the debugging stopped without any error

我创建了项目:dotnet new mvc 在一个 Meow 文件夹中，没什么特别的，然后添加了一个新的配置 .NET Core Launch (web).

I created the project with: dotnet new mvc in a Meow folder, nothing special, and then added a new configuration .NET Core Launch (web).

事实证明，tasks.json 中的 build 任务中定义的 dotnet build 只调用了 launch.json 的 >preLaunchTask 就是这样，调试过程开始和停止而不显示任何错误.

It turns out that there is only a call to dotnet build defined in the build task in tasks.json as defined in preLaunchTask of the launch.json and that's it the debugging process starts and stops without showing any error.

当运行 dotnet run 时，一切正常，所以我怀疑问题更多地来自我的 Visual Studio 调试配置.

When running dotnet run, everything works, so I am suspecting the issue comes more from my Visual Studio debug configuration.

在终端选项卡中，我有:

In terminal tab I have:

> Executing task: dotnet build /home/perret/Desktop/Playground/CSharpmusement/Meow/Meow.csproj <

Microsoft (R) Build Engine version 15.9.20.63311 for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

  Restore completed in 86.18 ms for /home/perret/Desktop/Playground/CSharpmusement/Meow/Meow.csproj.
  Meow -> /home/perret/Desktop/Playground/CSharpmusement/Meow/bin/Debug/netcoreapp2.2/Meow.dll
  Meow -> /home/perret/Desktop/Playground/CSharpmusement/Meow/bin/Debug/netcoreapp2.2/Meow.Views.dll

Build succeeded.
    0 Warning(s)
    0 Error(s)

Time Elapsed 00:00:04.62

Terminal will be reused by tasks, press any key to close it.

下面两个自动生成的文件看起来不错.

The two files below that have been auto generated look fine.
