Dependency Injection

Register all the needed part into your DI container

Becoming a super hero is a fairly straight forward process and one step of this process is to use a dependency injection container.

All you need to do is this:

/// <summary>
/// Add StackExchange.Redis with its serialization provider.
/// </summary>
/// <param name="services">The service collection.</param>
/// <param name="redisConfiguration">The redis configration.</param>
/// <typeparam name="T">The typof of serializer. <see cref="ISerializer" />.</typeparam>
public static IServiceCollection AddStackExchangeRedisExtensions<T>(
        this IServiceCollection services,
        Func<IServiceProvider, IEnumerable<RedisConfiguration>> redisConfigurationFactory)
        where T : class, ISerializer
    {
        services.AddSingleton<IRedisClientFactory, RedisClientFactory>();
        services.AddSingleton<ISerializer, T>();

        services.AddSingleton((provider) => provider
            .GetRequiredService<IRedisClientFactory>()
            .GetDefaultRedisClient());

        services.AddSingleton((provider) => provider
            .GetRequiredService<IRedisClientFactory>()
            .GetDefaultRedisClient()
            .GetDefaultDatabase());

        services.AddSingleton(redisConfigurationFactory);

        return services;
    }

There are two important things to know in this code block:

• How to retrieve an instance of the redis configuration (here the solution);
• Choose the right serializer (here few options)
