Visual Studio作为宇宙第一的IDE，开发调试.net core app，无一能出其右，我们还需要去了解Visual Studio Code吗？答案是肯定。

• 杀鸡焉用牛刀：就一个hello world的Console App，还需要打开Visual Studio吗？

• 画地为牢：如果开发环境换成Ubuntu或Centos等任意一个Linux发行版，调试怎么办？

• 兵贵神速：马上就要开始调试一个已有app，但是调试环境没有Visual Studio，安装是不是特别费时？甚至不支持Visual Studio,怎么办？

那么Visual Studio Code的小而美的优势就会体现出来。

1.安装Visual Studio Code

纯属混字数的，扔一个链接https://code.visualstudio.com/，下载去吧，

• windows下就是傻瓜式下一步下一步。

• 红帽系linux

• • https://code.visualstudio.com/docs/setup/linux#_rhel-fedora-and-centos-based-distributions

• debian或者ubuntu

• • https://code.visualstudio.com/docs/setup/linux#_debian-and-ubuntu-based-distributions

• MacOS

• • https://code.visualstudio.com/docs/setup/mac

2.安装.net core sdk

同样是扔一个链接https://dotnet.microsoft.com/download，页面选项卡，有4种环境

• Windows

• Linux

• MacOS

• Docker

按需选择吧

3.编码

略过

4.调试配置

假设你已经编码完成，

F5开始调试->Select Envoriment->.net core

4.1 生成并修改launch.json

然后就会创建.vscode文件夹，且创建了launch.json

{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": ".NET Core Launch (web)","type": "coreclr","request": "launch","preLaunchTask": "build","program": "${workspaceFolder}/Vmware.Sphere.Api/bin/Debug/netcoreapp3.1/properties/netcoreapp3.1/Vmware.Sphere.Api.dll","args": [],"cwd": "${workspaceFolder}/Vmware.Sphere.Api","stopAtEntry": false,"serverReadyAction": {"action": "openExternally","pattern": "\\bNow listening on:\\s+(https?://\\S+)"},"env": {"ASPNETCORE_ENVIRONMENT": "Development"},"sourceFileMap": {"/Views": "${workspaceFolder}/Views"}},{"name": ".NET Core Attach","type": "coreclr","request": "attach","processId": "${command:pickProcess}"}]
}

• program:调试的dll路径

• cwd:正在调试的程序的工作目录的路径。默认是当前工作区

其他属性，还想知道具体作用，鼠标悬停在launch.json的某一个属性上，就可以了解，并根据实际情况进行修改。

4.2 生成task.json

F5->Could not find the task 'build'->Configure Task->Select a task to configure->Create  task.json file from temple->.Net Core

就会继续在.vscode下创建task.json

{// See https://go.microsoft.com/fwlink/?LinkId=733558// for the documentation about the tasks.json format"version": "2.0.0","tasks": [{"label": "build","command": "dotnet","type": "shell","args": ["build",// Ask dotnet build to generate full paths for file names."/property:GenerateFullPaths=true",// Do not generate summary otherwise it leads to duplicate errors in Problems panel"/consoleloggerparameters:NoSummary"],"group": "build","presentation": {"reveal": "silent"},"problemMatcher": "$msCompile"}]
}

• preLaunchTask:"build",Task to run before debug session starts.在启动调试会话之前运行的任务，说白了，就是调试之前，总得构建生成吧。然后就会触发task中lable名为build的构建任务

• • command+args=dotnet build ...

5.调试快捷键

• Continue / Pause F5

• Step Over F10

• Step Into F11

• Step Out Shift+F11

• Restart Ctrl+Shift+F5

• Stop Shift+F5

• Run (Start Without Debugging) action is triggered with Ctrl+F5

现在就可以正常调试了

• 断点

• 日志断点

• 变量监控

• 等等
