When using double underscores in AAC keys the configuration fails to load hierarchical structure and Options pattern fails

When using double underscores in AAC keys the configuration fails to load hierarchical structure and Options pattern fails.

Double underscores are supported from environment variables and are correctly turned into keys with colons which are then available to the Options pattern.

This same feature fails when keys with double underscores are loaded from AAC as described in more detail here

Hi, @brgrz

Can you try this workaround?

var appConfig = new ConfigurationBuilder()
    .AddAzureAppConfiguration(options =>
    {
        options.Connect(Environment.GetEnvironmentVariable("ConnectionString"));
        options.Map((setting) =>
        {
            setting.Key = setting.Key.Replace("__", ":");
            return new ValueTask<ConfigurationSetting>(setting);
        });
    })
    .Build();

We have a Map api. #355

I have a key App__Test__Key in my app config store.

Using Map api can meet your need.
