Outline the useful resource
In REST (an acronym for Representational State Switch), a useful resource is outlined as a chunk of knowledge that may be accessed utilizing a novel URI (Uniform Useful resource Identifier). Sometimes, the useful resource is described utilizing a mannequin object. On this instance, our useful resource will probably be an occasion of the Article class.
Within the venture we simply created, create a brand new file named Article.cs and write the next code in there to create our useful resource kind.
public class Article
   {
       public int Id { get; set; }
       public string Title { get; set; }
       public string Description { get; set; }
       inner readonly string Creator;
   }
Create a repository for the useful resource
In an ASP.NET Core software a repository is used to supply entry to the info retailer. On this instance, we’ll create an article repository that consists of two varieties — the IArticleRepository interface and the ArticleRepository class that implements this interface.
Create an interface named IArticleRepository in a file having the identical identify with a .cs extension and substitute the default generated code with the next code.
public interface IArticleRepository
   {
       public Article GetArticle(int id);
       public Checklist GetArticles();
   }
Subsequent create the ArticleRepository class. The ArticleRepository class implements the strategies of the IArticleRepository interface as proven within the code snippet given beneath.
public class ArticleRepository : IArticleRepository
   {
       public Article GetArticle(int id)
       {
           throw new NotImplementedException();
       }
       public Checklist GetArticles()
       {
           throw new NotImplementedException();
       }
   }
Register the repository within the Program.cs file
You must now register the ArticleRepository class as a service utilizing the next line of code within the Program.cs file.
