Distributed Caching with Redis in .NET

Install Microsoft.Extensions.Caching.StackExchangeRedis nuget package

Add RedisConfiguration section to your appsettings.json

"RedisConfiguration": {
   "Host": "your-awesome.host.com",
   "Port": 6379,
   "IsSSL": true,
   "Password": "YourSecur3Pa$$w0rD"
}

and create a matching options model for binding

internal class RedisConfigurationOptions
{
   public string Host { get; set; } = string.Empty;
   public int Port { get; set; }
   public bool Ssl { get; set; } = true;
   public string Password { get; set; } = string.Empty;
}

Configure it in the DI container

// Configure Redis
var redisConfig = configuration
   .GetSection("RedisConfiguration")
   .Get<RedisConfigurationOptions>()
   ?? throw new InvalidOperationException("RedisConfiguration is missing or invalid.");
   
services.AddSingleton<IConnectionMultiplexer>(option => ConnectionMultiplexer.Connect(
   new ConfigurationOptions
   {
       EndPoints = { $"{redisConfig.Host}:{redisConfig.Port}" },
       AbortOnConnectFail = false,
       Ssl = redisConfig.Ssl,
       Password = redisConfig.Password,
   }));
   
services.AddDistributedMemoryCache();
