 First, you can configure the hybrid cache options in your module class as below (it's optional):

 After the configuration, now you can inject the `IHybridCache` and use it to set and retrieve cache values:

-    public string Name { get; set; }
-
-    public int PageCount { get; set; }

 * You can use the `IHybridCache<TCacheItem>` or `IHybridCache<TCacheItem, TCacheKey>` service to leverage the hybrid caching. If you use `IHybridCache<TCacheItem>`as the service, then you should pass the cache key as *string* like in the example above.
