Configure

Startup.cs

Single Server

public void ConfigureServices(IServiceCollection services)
{
    services.AddDistributedServiceStackRedisCache(options =>
    {
        // default single server: 127.0.0.1:6379
        // services.AddServiceStackRedisCache();
        
        // customize single server
        services.AddServiceStackRedisCache(options =>{
        	options.SingleServer = "[email protected]:6379";
        });
    }
                                                  
    services.AddControllers();
}

Read and write separation

public void ConfigureServices(IServiceCollection services)
{
    services.AddServiceStackRedisCache(options =>
    {
        options.ReadWriteServers = new[]
        {
            "192.168.1.1:6379", "[email protected]:6379", "[email protected]:6379", "[email protected]:6379"
        };
        options.ReadOnlyServers = new[]
        {
            "192.168.1.1:6379", "[email protected]:6379"
        };
    });

    services.AddControllers();
}

Load from configuration

public void ConfigureServices(IServiceCollection services)
{
   
services.AddServiceStackRedisCache(Configuration.GetSection("ServiceStackRedisOptions"));

    services.AddControllers();
}

        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"

    }

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()

            array = Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            }).ToArray();

            // Cache for 30 minutes
            _redisCache.Set("WeatherForecast", array, 60 * 1 * 30);
