Implementing a distributed cache

As we mentioned previously, ASP.NET Core allows us to implement distributed caching. In this section, we will learn how to use Redis as a form of cache storage. It is possible to extend the behavior of the caching mechanism of ASP.NET Core by adding and executing the following CLI instruction in the Catalog.API project:

 dotnet add package Microsoft.Extensions.Caching.Redis

By doing this, we can connect the Redis server and use it by adding the following extension method to the Startup class:

public class Startup
    {
        ...
        public void ConfigureServices(IServiceCollection services)
        {
            ...
            services
                .AddDistributedRedisCache(
                       options => { options.Configuration = 
                       "catalog_cache:6380";
                });
               ...
        }
    }
}
