How to set up Distributed Redis Cache in .NET Core

In the world of web development, optimizing performance is a key concern.

We can boost performance by implementing distributed caching.

Today, our experts are going to take us through implementing distributed caching with Redis in a .NET Core application. This will result in faster response times and better scalability.

Before we begin, we need the following in place:

• .NET Core SDK 2.2 or later
• Visual Studio 2017 or later
• Redis server

1. First, open Visual Studio and create a new project.
2. Then, select the Console App (.NET Core) template, enter a name for our project, and click Create.
3. Now, right-click on the project in the Solution Explorer.
4. Next, select “Manage NuGet Packages” and search for “StackExchange.Redis”. Then install it.
5. Now, it is time to connect to the Redis server by creating a Redis client via the ConnectionMultiplexer class:

   var redis = ConnectionMultiplexer.Connect("localhost");
var db = redis.GetDatabase();

6. Then, cache data in Redis using the Set() method:

   db.StringSet("key", "value");

   Additionally, we can set an expiration time:

   db.StringSet("key", "value", TimeSpan.FromMinutes(5));
7. We can retrieve cached data from Redis with this:

   var value = db.StringGet("key");
8. At this point, we have to create a Redis cache provider by implementing the IDistributedCache interface:

   
public class RedisCacheProvider : IDistributedCache
{
// Implementation details...
}

9. Now, register the Redis cache provider in the .NET Core application:

   
services.AddDistributedRedisCache(options =>
{
options.Configuration = "localhost";
options.InstanceName = "SampleInstance";
});

10. Then, inject the IDistributedCache interface and use the Redis cache provider in our application:

    
public class HomeController : Controller
{
private readonly IDistributedCache _cache;

    public HomeController(IDistributedCache cache)
    {
    _cache = cache;
    }

    public IActionResult Index()
    {
    var data = _cache.GetString(“key”);

    if (string.IsNullOrEmpty(data))
    {
    // Cache miss
    data = “Hello, World!”;
    var options = new DistributedCacheEntryOptions()
    .SetSlidingExpiration(TimeSpan.FromMinutes(5));
    _cache.SetString(“key”, data, options);
    }
    else
    {
    // Cache hit
    }

    return Content(data);
    }
    }

With the above steps, we will be able to efficiently cache and retrieve data, leading to faster response times and a more responsive user experience.
