How to target platforms with launch.json - windows

Question

The omnisharp ReadMe says this:
Operating System Specific Configurations
If there specific commands
that need to be changed per operating system, you can use the fields:
'windows', 'osx', or 'linux'. You can replace any of the fields
mentioned above for the specific operating system.
This is my launch.json file:
{
"version": "0.2.0",
"configurations": [
{
"name": ".NET Core Launch (console)",
"type": "coreclr",
"request": "launch",
"preLaunchTask": "build",
"program": "${workspaceFolder}/TestConsole/bin/Debug/netcoreapp2.1/TestConsole.dll",
"args": [
"c:\\git\\core\\XunitTestLib\\Steps\\",
// "~/../../XunitTestLib/Steps"
],
"cwd": "${workspaceFolder}/TestConsole",
"console": "internalConsole",
"stopAtEntry": false,
"internalConsoleOptions": "openOnSessionStart"
},
{
"name": ".NET Core Attach",
"type": "coreclr",
"request": "attach",
"processId": "${command:pickProcess}"
},
]
}
When debugging I want to builds on Windows to start with the "args" entry which is uncommented, but on mac os I want it to start with the line which is commented out.
I am assuming that I would duplicate the configuration, once for Windows and mac, each, but this statement is confusing:
You can replace any of the fields mentioned above for the specific operating system.
It appears to be saying that I can replace "args" with "osx" but that obviously does not work.
How do I create a configuration for a target platform?

Answer 1

Turns out that targeting multiple platforms is a lot easier than I expected and is explained here with regards to the tasks.json file (but works just the same for launch.json).
My launch.json file adjusted for osx and windows would look like this:
{
"version": "0.2.0",
"configurations": [
{
"name": ".NET Core Launch (console)",
"type": "coreclr",
"request": "launch",
"preLaunchTask": "build",
"program": "${workspaceFolder}/TestConsole/bin/Debug/netcoreapp2.1/TestConsole.dll",
"windows": {
"args": [
"c:\\git\\core\\XunitTestLib\\Steps\\"
]
},
"osx": {
"args": [
"~/../../XunitTestLib/Steps"
]
},
"cwd": "${workspaceFolder}/TestConsole",
"console": "internalConsole",
"stopAtEntry": false,
"internalConsoleOptions": "openOnSessionStart"
},
{
"name": ".NET Core Attach",
"type": "coreclr",
"request": "attach",
"processId": "${command:pickProcess}"
},
]
}
