\u0130\u00e7erik olarak Redis veri t\u00fcrlerine \u00e7ok temas etmeden y\u00fczeysel cacheleme yapmam\u0131z\u0131 sa\u011flayan ‘StackExchangeRedisCache’ y\u00f6ntemini uygulayaca\u011f\u0131m\u0131z\u0131, esas Redis’e tam teferruatl\u0131 y\u00f6netimi bir sonraki makalede ele alaca\u011f\u0131m\u0131z\u0131 bildirerek konuya ba\u015flayal\u0131m.<\/p>\n

Kullan\u0131lacak K\u00fct\u00fcphane ve Servisler<\/h3>\n

Bir Asp.NET Core uygulamas\u0131nda Redis DistributedCache kullanabilmek i\u00e7in ilk olarak uygulamaya Microsoft.Extensions.Caching.StackExchangeRedis<\/a> k\u00fct\u00fcphanesinin dahil edilmesi gerekmektedir. Ard\u0131ndan ‘Startup.cs’ dosyas\u0131ndan a\u015fa\u011f\u0131daki gibi ‘AddStackExchangeRedisCache’ mod\u00fcl\u00fc uygulamaya eklenmelidir. Burada dikkat edilmesi gereken husus Redis server\u0131n ayakta olmas\u0131d\u0131r.<\/p>\n
