IConfiguration extensions for Azure App Config Service

Example using Connection String

 Host.CreateDefaultBuilder(args)
    .ConfigureAppConfiguration((hostContext, builder) =>
    {
        var environmentName = hostContext.HostingEnvironment.EnvironmentName;
        builder
            .SetBasePath(hostContext.HostingEnvironment.ContentRootPath)
            .AddJsonFile("appsettings.json", false, true)
            .AddJsonFile($"appsettings.{environmentName}.json", true)
            .AddEnvironmentVariables()
            .AddCommandLine(args);

        builder.AddUserSecrets<Program>();

        var settings = builder.Build();
        var connectionString = settings.GetValue<string>("AZURE_APP_CONFIG_CONNECTION_STRING") ?? Environment.GetEnvironmentVariable("AZURE_APP_CONFIG_CONNECTION_STRING");

        builder.AddAzureAppConfiguration(options =>
        {
            options
                .Connect(connectionString)
                .OltAzureConfigDefault(new OltOptionsAzureConfig("AppKeyPrefix:", RunEnvironment)); // AppKeyPrefix: will be trimmed from the configuration
        });
    })

Example using Azure Identity

 Host.CreateDefaultBuilder(args)
    .ConfigureAppConfiguration((hostContext, builder) =>
    {
        var environmentName = hostContext.HostingEnvironment.EnvironmentName;
        builder
            .SetBasePath(hostContext.HostingEnvironment.ContentRootPath)
            .AddJsonFile("appsettings.json", false, true)
            .AddJsonFile($"appsettings.{environmentName}.json", true)
            .AddEnvironmentVariables()
            .AddCommandLine(args);

        builder.AddUserSecrets<Program>();

        var settings = builder.Build();

        var endpoint = settings.GetValue<string>("AZURE_APP_CONFIG_ENDPOINT") ?? Environment.GetEnvironmentVariable("AZURE_APP_CONFIG_ENDPOINT");

        builder.AddAzureAppConfiguration(options =>
        {
            options
                .Connect(endpoint, new EnvironmentCredential())
                .OltAzureConfigDefault(new OltOptionsAzureConfig("AppKeyPrefix:", RunEnvironment)); // AppKeyPrefix: will be trimmed from the configuration
        });
    })
