Program.cs

using Aguacongas.DynamicConfiguration.Redis;
using Yarp.Configuration.Model;
using Swashbuckle.AspNetCore.SwaggerUI;
using Aguacongas.DynamicConfiguration.WebApi.Controllers;

var builder = WebApplication.CreateBuilder(args);

var configuration = builder.Configuration;
// Add Redis configuration provider.
configuration.AddRedis(options => configuration.GetSection(nameof(RedisConfigurationOptions)).Bind(options));

var services = builder.Services;
// Add services to the container.
services.Configure<ReverseProxyOptions>(configuration.GetSection(nameof(ReverseProxyOptions)))
    .AddAuthorization(options =>
    {
        // The web api requires 2 policies, DYNAMIC_CONFIGURATION_READER_POLICY and DYNAMIC_CONFIGURATION_WRITTER_POLICY
        // In this sample those policies requires nothing, all users have access to the api.
        // You should update this code to meet your requirement.
        options.AddPolicy(ConfigurationController.DYNAMIC_CONFIGURATION_READER_POLICY, 
            builder => builder.RequireAssertion(context => true));
        options.AddPolicy(ConfigurationController.DYNAMIC_CONFIGURATION_WRITTER_POLICY, 
            builder => builder.RequireAssertion(context => true));
    });

services.AddAuthentication(); // this sample doesn't have authentication system but shoudl add yours.

services.AddControllersWithViews()
    .AddConfigurationWebAPI(builder.Configuration, options => options.Provider = ((IConfigurationRoot)configuration).Providers.First(p => p is RedisConfigurationProvider));
    
services.AddRazorPages();

services.AddSwaggerGenFromConfiguration(configuration);

var app = builder.Build();

// Auto reload the configuration when changes occur.
app.SubscribeToConfigurationChanges();

// Configure the HTTP request pipeline.
