You don’t need to edit JSON files and push changes to have different configuration settings in different slots. You can manage configuration in the Portal for that.
This is a .NET 6 app, and the native JSON config format is nested. The App Service configuration doesn’t support that so you need to flatten out the hieararchy, using double underscores __ to denote the levels.
So this setting in JSON:
{
"app" : {
"config": {
"setting" : 4
}
}
}
Would be represented as a setting with the key app__config__setting.
