[英]Visual Studio Code debugging the default ASP.NET Core MVC WebApp: does not work
I am using Manjaro linux and tried to debug the default ASP.NET Core MVC project but the debugging stopped without any error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
I created the project with: dotnet new mvc
in a Meow
folder, nothing special, and then added a new configuration .NET Core Launch (web)
.我创建了项目: dotnet new mvc
in a Meow
文件夹,没什么特别的,然后添加了一个新的配置.NET Core Launch (web)
。
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.事实证明,只有一个调用dotnet build
的定义build
的任务tasks.json
中定义preLaunchTask
中的launch.json
,这就是它的调试过程开始,而不显示任何错误停止。
When running dotnet run
, everything works, so I am suspecting the issue comes more from my Visual Studio debug configuration.运行dotnet run
,一切正常,所以我怀疑问题更多地来自我的 Visual Studio 调试配置。
In terminal tab I have:在终端选项卡中,我有:

I answered my own question on those GitHub issues:我在这些 GitHub 问题上回答了我自己的问题:
Basically steps of my solution on a fresh Manjaro Gnome variant live session:我在新的 Manjaro Gnome 变体实时会话中的解决方案的基本步骤:
Install ~~ yay
to enjoy AUR without struggling with the command line: sudo pacman -Sy yay
~~ yay -S dotnet-sdk mono binutils msbuild-stable visual-studio-code-bin --noconfirm
(see the [UPDATE] below).安装 ~~ yay
享受 AUR,而无需在命令行中挣扎: sudo pacman -Sy yay
~~ yay -S dotnet-sdk mono binutils msbuild-stable visual-studio-code-bin --noconfirm
(请参阅下面的 [更新]) .
Setup everything you need (aka the .NET Core SDK, Mono, MSBuild and Visual Studio Code Insiders): yay -S dotnet-sdk mono binutils msbuild-stable visual-studio-code-insiders --noconfirm
设置您需要的一切(又名 .NET Core SDK、Mono、MSBuild 和 Visual Studio Code Insiders): yay -S dotnet-sdk mono binutils msbuild-stable visual-studio-code-insiders --noconfirm
binutils
cause the Gnome variant does not seem to embed that one natively, and this require for stripping in one of the steps of the msbuild-stable
installation.注意: binutils
导致 Gnome 变体似乎没有在本机嵌入该变体,这需要在msbuild-stable
安装的步骤之一中进行剥离。 Add the required environment variables that you would like to export at the end of your .bashrc
file in your home folder:在您的主文件夹中的.bashrc
文件末尾添加您想要导出的所需环境变量:
export MSBuildSDKsPath=/opt/dotnet/sdk/$(dotnet --version)/Sdks
export PATH="$PATH:/home/manjaro/.dotnet/tools"
Create a dummy project: dotnet new mvc
创建一个虚拟项目: dotnet new mvc

This is not stable though, as pointed by one of the comments in my initial post, Arch / Manjaro are not officially supported by the debugger, but I found that this is more related to the version of Visual Studio Code, atm it only worked with the insiders edition for some reasons I completely ignore.不过,这并不稳定,正如我最初的帖子中的一条评论所指出的,调试器不正式支持 Arch / Manjaro,但我发现这与 Visual Studio Code 的版本更相关,atm 仅适用于由于某些原因我完全忽略了内部人士版。
I will keep this answer updated whenever I will notice that I will no longer need to resort to the Insiders Edition.每当我注意到我将不再需要使用 Insiders Edition 时,我都会更新此答案。
[UPDATE] The official Visual Code AUR page shows the different versions available: [更新]官方 Visual Code AUR 页面显示了可用的不同版本:
The following packages provide VSCode:以下软件包提供了 VSCode:
- code (open-source release)代码(开源版本)
- visual-studio-code-bin AUR (Microsoft-branded release) visual-studio-code-bin AUR(微软品牌版本)
- code-git AUR (in-development open-source version) code-git AUR(开发中的开源版本)
I think I may have had installed the wrong version at first (the non insiders one was the open source release: code
.我想我一开始可能安装了错误的版本(非内部人员是开源版本: code
.
Actually when playing with the official tar.gz
from the website (which is the hard way equivalent of installing visual-studio-code-bin
) it worked fine.实际上,当使用网站上的官方tar.gz
(这是一种相当于安装visual-studio-code-bin
的困难方式),它运行良好。
The right way is to (obviously) go with the official Microsoft branded release: visual-studio-code-bin
.正确的方法是(显然)使用官方的 Microsoft 品牌版本: visual-studio-code-bin
。
