Redis Cache in ASP.NET Core

Question

I am new to Redis and using using VS 2015 and ASP.NET Core app (v 1.0), I installed the nugget package:

Install-Package StackExchange.Redis

However I am not able to inject and configure it into my services, there is no RedisCache or "AddDistributedRedisCache" method.

How can I inject and use it?

Answer 1

01.Download latest redis from download ,install and start the redis service from services.msc

02.Add two library in project.json

"Microsoft.Extensions.Caching.Redis.Core": "1.0.3",
"Microsoft.AspNetCore.Session": "1.1.0",

03.Add you dependency injection in

public void ConfigureServices(IServiceCollection services)
    {
        services.AddApplicationInsightsTelemetry(Configuration);

        services.AddMvc();
        //For Redis
        services.AddSession();
        services.AddDistributedRedisCache(options =>
        {
            options.InstanceName = "Sample";
            options.Configuration = "localhost";
        });
  } 

4. and in Configure method add top of app.UseMvc line

   app.UseSession();

to use redis in session storage in asp.net core .Now you can use like this in HomeController.cs

public class HomeController : Controller
{
    private readonly IDistributedCache _distributedCache;
    public HomeController(IDistributedCache distributedCache)
    {
        _distributedCache = distributedCache;
    }
    //Use version Redis 3.22
    //http://stackoverflow.com/questions/35614066/redissessionstateprovider-err-unknown-command-eval
    public IActionResult Index()
    {
        _distributedCache.SetString("helloFromRedis", "world");
        var valueFromRedis = _distributedCache.GetString("helloFromRedis");
        return View();
    }
 }
