How do I designate a startup project in VS Code?

Question

How do I designate a startup project in VS Code?

Context:

In Visual Studio, I right click a project within solution explorer and set it as startup.

However, I am not clear on how to accomplish this in VS Code.

Note:

I recently added a WebAPI project to my directory in VS Code.

This maybe deserves a better answer. So let me explain. In Visual Studio Code you have to set up your startup projects all in the launch.json and the tasks.json files.

Here is a small detailed introduction:

1. Choose a root project folder (i.e.: D:/anyfolder/myrootfolder)
   

2. Create two folders for two projects in the root folder
   2.1 D:/anyfolder/myrootfolder/project1
   2.2 D:/anyfolder/myrootfolder/project2
   

3. Open cmd and create two Console-Applications (I use .netcore 2.0)
   3.1 go to folders project1 and project2 using cmd (Command: cd -foldername-)
   3.2 for each of that folders execute the command: dotnet new console
   

4. Open the root project folder with Visual Studio Code
   

5. Add the following launch.json and tasks.json to the .vscode folder (usually the .vscode folder is generated after clicked the debug-button in VS Code)

Sample launch.json file:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch Project1",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceRoot}/project1/bin/Debug/netcoreapp2.0/project1.dll",
            "args": [],
            "cwd": "${workspaceRoot}/project1",
            "stopAtEntry": false,
            "console": "internalConsole"
        },
        {
            "name": ".NET Core Launch Project2",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceRoot}/project2/bin/Debug/netcoreapp2.0/project2.dll",
            "args": [],
            "cwd": "${workspaceRoot}/project2",
            "stopAtEntry": false,
            "console": "internalConsole"
        }
    ]
}

Sample tasks.json file:

{
    "version": "0.1.0",
    "command": "dotnet",
    "isShellCommand": true,
    "args": [],
    "tasks": [
        {
            "taskName": "build",
            "args": [
                "${workspaceRoot}/project1/project1.csproj"
            ],
            "isBuildCommand": true,
            "problemMatcher": "$msCompile"
        },
        {
            "taskName": "build",
            "args": [
                "${workspaceRoot}/project2/project2.csproj"
            ],
            "isBuildCommand": true,
            "problemMatcher": "$msCompile"
        }
    ]
}

Don't forget that I used .netcore 2.0. If you use another Target Framework you have to customize the upper sample files of course.

After all you should now see two items in right of the Play(Debug-)button:
.NET Core Launch Project1 and
.NET Core Launch Project2

This worked for me and my purposes...
