App Settings Colon Delimiter Not Allowed

[nehme-bilal-ah]

Hi,

In my appsettings.json file I have settings like this:

  "AzureStorageSettings": {
    "ConnectionString": "",
    "TableName": "Foo"
  }

I want to override the value of AzureStorageSettings:ConnectionString configuration with a secret stored in Azure Devops. In the past, I used to simply add -AzureStorageSettings:ConnectionString $(AzureStorageConnectionString) to the App settings section of the task and that worked perfectly.

However, with version 4, I get an error saying that colon character is not allowed. Is there a new way of achieving this or a way that I can espace the colon character? I tried everything that I can think of.

The solution is to use __ instead of : in App settings. The app settings get added as environment variables and Microsoft.Extensions.Configuration can handle __ for nesting configs.
