ASP.NET Core 3 and React

Implementing a data cache

We are going to implement a cache for the questions using the memory cache in ASP.NET Core:

1. First, let's create an interface in the Data folder called IQuestionCache:

using QandA.Data.Models;namespace QandA.Data{  public interface IQuestionCache  {    QuestionGetSingleResponse Get(int questionId);    void Remove(int questionId);    void Set(QuestionGetSingleResponse question);  }}

So, we need the cache implementation to have methods for getting, removing, and updating an item in the cache.

2. Now, we can create a class in the Data folder called QuestionCache:

using Microsoft.Extensions.Caching.Memory; using QandA.Data.Models;namespace QandA.Data{  public class QuestionCache: IQuestionCache  {    // TODO - create a memory cache
