Usage:

Step 1: Create application in AppConfig. Provide name as "AppConfigDemo". Create environment under project named as "Development". Create configuration iwth name, "queueConfigurationProfile".
Provide value of configuration as below.

{ Kafka: { "BootstrapServers": "localhost", "Producer": { "ClientId": "19", "StatisticsIntervalMs": 5000, "MessageTimeoutMs": 10000, "SocketTimeoutMs": 10000, "ApiVersionRequestTimeoutMs": 10000, "MetadataRequestTimeoutMs": 5000, "RequestTimeoutMs": 5000 }, "Consumer": { "GroupId": "49", "EnableAutoCommit": true, "StatisticsIntervalMs": 5000, "SessionTimeoutMs": 10000 } },
RabbitMQ : { "Uri": "localhost", "UserName": "root@3", "Password": "SWAMI", "DispatchConsumersAsync": true } }

Step 2: Add reference of Amazon.Extensions.Configuration.AppConfig project. Add extesion in using following code in Program.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureAppConfiguration((hostingContext, config) =>
        {
            config
                .AddAWSAppConfigConfiguration("AppConfigDemo",
                Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"),
                "queueConfigurationProfile",
                new Guid().ToString());
        })
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

Step 3: Access configuration in code.
Startup.cs - Options pattern

services.Configure<KafkaConfig>(Configuration.GetSection("Kafka"));
services.Configure<RabbitMQConfig>(Configuration.GetSection("RabbitMQ"));
