未知错误：0x800700c1，在VS Code中调试.net Core 3.0 API时

问题描述

我正在用3.0构建.Net Core API。

一周前一切运行良好，几天后，当我尝试调试时，它会抛出一个奇怪的错误，如左下角的以下屏幕截图所示。

并且调试器此时已停止。

以下是我的.vscode> launch.jason文件

{
"version": "0.2.0","configurations": [
        {
            "name": ".NET Core Launch (web)","type": "coreclr","request": "launch","preLaunchTask": "build",// If you have changed target frameworks,make sure to update the program path.
            "program": "${workspaceFolder}/bin/Debug/netcoreapp3.0/WebApi.dll","args": [],"cwd": "${workspaceFolder}","stopAtEntry": false,// Enable launching a web browser when ASP.NET Core starts. For more information: https://aka.ms/VSCode-CS-LaunchJson-WebBrowser
            "serverReadyAction": {
                "action": "openExternally","pattern": "\\bNow listening on:\\s+(https?://\\S+)"
            },"env": {
                "ASPNETCORE_ENVIRONMENT": "Development"
            },"sourceFileMap": {
                "/Views": "${workspaceFolder}/Views"
            }
        },{
            "name": ".NET Core Attach","request": "attach","processId": "${command:pickProcess}"
        }
    ]
}

以下是我的WebApi.csproj

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="AutoMapper" Version="9.0.0" />
    <PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="7.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="3.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Cors" Version="2.2.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.0.0">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="3.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0" />
    <PackageReference Include="System.IdentityModel.Tokens.Jwt" Version="5.5.0" />
  </ItemGroup>
</Project>

我尝试重新运行删除Debug文件夹的项目，但是没有解决。

解决方法

有同样的问题。该错误表示您向调试器发送了一个不是可执行文件的文件。 尝试验证是否在launch.json（程序属性）中正确配置了要调试的可执行文件的路径。
