Program.cs registration

var redisConfig = builder.Configuration.GetSection("Redis").Get<RedisConfiguration>();
builder.Services.AddStackExchangeRedisExtensions<SystemTextJsonSerializer>(redisConfig);
// Optional compression:
builder.Services.AddRedisCompression<LZ4Compressor>();

Azure Managed Identity

redisConfig.ConfigurationOptionsAsyncHandler = async opts =>
{
    await opts.ConfigureForAzureWithTokenCredentialAsync(new DefaultAzureCredential());
    return opts;
};

Sentinel configuration

var config = new RedisConfiguration
{
    ServiceName = "mymaster",
    Hosts = new[] {
        new RedisHost { Host = "sentinel1", Port = 26379 },
        new RedisHost { Host = "sentinel2", Port = 26379 },
    },
    IsDefault = true,
};

Multiple instances

var configs = new[]
{
    new RedisConfiguration { Name = "Cache", IsDefault = true, /* ... */ },
    new RedisConfiguration { Name = "Session", /* ... */ },
};
builder.Services.AddStackExchangeRedisExtensions<SystemTextJsonSerializer>(configs);

// Resolve: inject IRedisClientFactory, call GetRedisClient("Session")
