description	Generate StackExchange.Redis.Extensions configuration and DI registration from natural language requirements

Redis Configure

Generate complete RedisConfiguration and ASP.NET Core DI setup for StackExchange.Redis.Extensions based on the user's requirements.

When to use

When the user asks to:

• Set up Redis in their .NET project
• Configure connection pooling, Sentinel, TLS, Azure Managed Identity
• Choose a serializer or compressor
• Set up multiple Redis instances

How to respond

1. Ask clarifying questions if needed (single vs. multi-instance, cloud vs. local, auth method)
2. Generate the complete configuration

Configuration Reference

NuGet packages required

• StackExchange.Redis.Extensions.Core — always required
• StackExchange.Redis.Extensions.AspNetCore — for DI registration
• One serializer: System.Text.Json (recommended), Newtonsoft, MemoryPack, MsgPack, Protobuf, ServiceStack, Utf8Json
• Optional compressor: Compression.LZ4 (fastest), Compression.Snappier, Compression.ZstdSharp (best ratio), Compression.GZip (no deps), Compression.Brotli (best ratio for text)

appsettings.json structure

{
  "Redis": {
    "Password": "",
    "AllowAdmin": true,
    "Ssl": false,
    "ConnectTimeout": 5000,
    "SyncTimeout": 5000,
    "Database": 0,
    "Hosts": [{ "Host": "localhost", "Port": 6379 }],
    "PoolSize": 5,
    "IsDefault": true
  }
}

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")

Key properties

Property	Default	Description
PoolSize	5	Connection pool size
ConnectionSelectionStrategy	LeastLoaded	LeastLoaded or RoundRobin
SyncTimeout	5000	Sync timeout (ms)
ConnectTimeout	5000	Connect timeout (ms)
KeyPrefix	""	Prefix for all keys and channels
KeepAlive	-1	Heartbeat interval (seconds)
ClientName	null	Connection client name
MaxValueLength	0	Max serialized value size (0 = unlimited)

Serializer selection guide

Scenario	Recommended
General purpose	System.Text.Json
Legacy JSON.NET compatibility	Newtonsoft
Maximum performance (binary)	MemoryPack (net8.0+)
Cross-language compatibility	Protobuf or MsgPack

Compressor selection guide

Scenario	Recommended
Lowest latency (caching)	LZ4
Best compression ratio	ZstdSharp or Brotli
No external dependencies	GZip
