微服务实践之使用 Visual Studio 2022 调试Dapr 应用程序

安装配置相关软件

安装 PowerShell 7 / Core

dotnet tool install --global PowerShell

安装 Visual Studio 扩展 Microsoft Child Process Debugging Power Tool 2022

安装插件后启动 Visual Studio，可以在 Debug -> Other Debugging Targets 中找到 Child Process Debugging Settings。

这里save按钮要点，上面的保存按钮也要点

生成配置文件

<?xml version="1.0" encoding="utf-8"?>
<ChildProcessDebuggingSettings IsEnabled="true" xmlns="http://schemas.microsoft.com/vstudio/ChildProcessDebuggingSettings/2014">
  <DefaultRule Attach="false" />
  <Rule IsEnabled="true" ProcessName="dapr.exe" CommandLine="" EngineFilter="{3b476d35-a401-11d2-aad4-00c04f990171}" />
  <Rule IsEnabled="true" ProcessName="dotnet.exe" CommandLine="" EngineFilter="{3b476d35-a401-11d2-aad4-00c04f990171}" />
  <Rule IsEnabled="true" ProcessName="front.exe" CommandLine="" EngineFilter="{2e36f1d4-b23c-435d-ab41-18e608940038}" />

</ChildProcessDebuggingSettings>

修改launchSettings.json

{
  "profiles": {
    "http": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
