Example usage

Use IMemcachedClient interface

public class HomeController : Controller
{
 private readonly IMemcachedClient _memcachedClient;
 private readonly IBlogPostService _blogPostService;
 public HomeController(IMemcachedClient memcachedClient, IBlogPostService blogPostService)
 {
 _memcachedClient = memcachedClient;
 _blogPostService = blogPostService;
 }
 public async Task<IActionResult> Index()
 {
 var cacheKey = "blogposts-recent";
 var cacheSeconds = 600;
 var posts = await _memcachedClient.GetValueOrCreateAsync(
 cacheKey,
 cacheSeconds,
 async () => await _blogPostService.GetRecent(10));
 return Ok(posts);
 }
}

Use IDistributedCache interface

public class CreativeService
{
 private ICreativeRepository _creativeRepository;
 private IDistributedCache _cache;
 public CreativeService(
 ICreativeRepository creativeRepository,
 IDistributedCache cache)
 {
 _creativeRepository = creativeRepository;
 _cache = cache;
 }
 public async Task<IList<CreativeDTO>> GetCreatives(string unitName)
 {
 var cacheKey = $"creatives_{unitName}";
 IList<CreativeDTO> creatives = null;
 var creativesJson = await _cache.GetStringAsync(cacheKey);
 if (creativesJson == null)
 {
 creatives = await _creativeRepository.GetCreatives(unitName)
 .ProjectTo<CreativeDTO>().ToListAsync();
 var json = string.Empty;
 if (creatives != null && creatives.Count() > 0)
 {
 json = JsonConvert.SerializeObject(creatives);
 }
 await _cache.SetStringAsync(
 cacheKey, 
 json, 
 new DistributedCacheEntryOptions().SetSlidingExpiration(TimeSpan.FromMinutes(5)));
 }
 else
 {
 creatives = JsonConvert.DeserializeObject<List<CreativeDTO>>(creativesJson);
 }
 return creatives;
 }
}
