在Visual Studio Code中调试多个ASP.NET Core项目

Question

I have the following ASP.NET Core solution (solution.sln) structure in VS Code:

.vscode
  launch.json
  tasks.json
src/
  api/
    api.csproj
  web/
    web.csproj
test/
  api.test/
    api.test.csproj    
solution.sln

I need to debug both api.csproj and web.csproj so I added the launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Api",
      "type": "coreclr",
      "request": "launch",
      "preLaunchTask": "build",
      "program": "${workspaceRoot}/src/api/bin/Debug/netcoreapp1.1/api.dll",
      "args": [],
      "cwd": "${workspaceRoot}/src/api",
      "stopAtEntry": false,
      "console": "internalConsole"
    },
    {
      "name": "Web",
      "type": "coreclr",
      "request": "launch",
      "preLaunchTask": "build",
      "program": "${workspaceRoot}/src/web/bin/Debug/netcoreapp1.1/Nupaya.Api.dll",
      "args": [],
      "cwd": "${workspaceRoot}/src/web",
      "stopAtEntry": false,
      "launchBrowser": {
        "enabled": true,
        "args": "${auto-detect-url}",
        "windows": {
          "command": "cmd.exe",
          "args": "/C start ${auto-detect-url}"
        },
        "osx": {
          "command": "open"
        },
        "linux": {
          "command": "xdg-open"
        }
      },
      "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "sourceFileMap": {
        "/Views": "${workspaceRoot}/src/api/views"
      }
    }
  ]
} 

And the following tasks.json:

{
  "version": "0.1.0",
  "command": "dotnet",
  "isShellCommand": true,
  "args": [],
  "tasks": [
    {
      "taskName": "build",
      "args": ["Api", "Web"],
      "isBuildCommand": true,
      "showOutput": "always",
      "problemMatcher": "$msCompile"
    }
  ]
}  

But when I run it I get the following error:

MSBUILD : error MSB1008: Only one project can be specified.

I have tried different options but I always end with some kind of error.

Does anyone knows what is the proper way to debug multiple ASP.NET CORE projects in Visual Studio Code?

Modify your tasks.json file to the following:

{
  "version": "0.1.0",
  "command": "dotnet",
  "isShellCommand": true,
  "args": [],
  "options": {
    "cwd": "${workspaceRoot}"
  },
  "tasks": [
    {
      "taskName": "build",
      "args": [],
      "isBuildCommand": true,
      "showOutput": "always",
      "problemMatcher": "$msCompile"
    }
  ]
}

This should build your whole solution.

To debug one of the project switch to Debug View, choose a configuration and then click Start Debugging button as shown on the screenshot below
