如何解决Visual Studio Code调试ASP.NET MVC Core启动异常问题

基础配置信息 #

项目.csproj文件内容 #

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <UserSecretsId>aspnet-XXXXXXX-941AF9EA-C0DF-419D-B0F8-69FE3A477A65</UserSecretsId>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <OutputPath>$(SolutionDir)Builds\Debug\</OutputPath>
    <AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
    <AppendRuntimeIdentifierToOutputPath>false</AppendRuntimeIdentifierToOutputPath>
    <AddRazorSupportForMvc>true</AddRazorSupportForMvc>
  </PropertyGroup>
</Project>

launch.json配置内容 #

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": ".NET Core Launch (web)",
      "type": "coreclr",
      "request": "launch",
      "preLaunchTask": "watch",
      "program": "${workspaceFolder}/Builds/Debug/XXXXXXX.dll",
      "args": [],
      "cwd": "${workspaceFolder}",
      "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}"
    }
  ]
}

异常现象 #

• 在代码中设置断点后启动调试，编译正常完成，但不会自动启动浏览器，构建输出内容显示在终端而非调试控制台，终端输出如下：

Executing task: dotnet watch run /Users/omatrot/Documents/bealink/bealink_server/XXXXXXX/XXXXXXX/XXXXXXX.csproj /property:GenerateFullPaths=true /consoleloggerparameters:NoSummary <

• 按下CTRL+C终止托管进程后，VS Code会立即重新运行应用，此时输出自动切换到调试控制台，同时自动打开浏览器，断点可正常命中。

解决方案 #

移除项目中的如下NuGet包引用即可正常调试：

<PackageReference Include="Microsoft.Web.LibraryManager.Build" Version="2.1.113" />
