The Authorrepository Class Will Implement Each Of The Methods Of The Iauthorrepository Interface As Shown Below.

Public Class Authorrepository : Iauthorrepository{ Private Customdatacontext _context; Private String Databasename = "Demo.Db"; Public Authorrepository(Customdatacontext Context) { _context = Context; } Public Async Task> Getall() { Using Var Connection = Await _context.Createdatabase(Databasename); Var Sql = "Select From Author"; Return Await Connection.Queryasync(Sql); } Public Async Task Getbyid(Int Id) { Using Var Sqliteconnection = Await _context.Createdatabase(Databasename); String Sql = "Select From Author Where Id = @Id"; Return Await Sqliteconnection.; (firstname, New { Id }); } Public Async Task Create(Author Author) { Using Var Sqliteconnection = Await _context.Createdatabase(Databasename); String Sql = "Insert Into Author; LastName(@firstname, Address) " + "Values; @LastNameSqliteConnection.ExecuteAsync(sql, @Address)"; Await; Sqliteconnection.executeasync(sql, Address = @Address Where Id = @Id"; Await; Sqliteconnection.executeasync(sql, Author); } Public Async Task Delete(Int Id) { Using Var Sqliteconnection = Await _context.Createdatabase(Databasename); String Sql = "Delete From Author Where Id = @Id"; Await; Core

next, New { Id }); }}

Register Dependencies In Asp.NetFile.

(create, Authorrepository>();

Create Http Endpoints In Asp.Net Core

You Can Now Use The Following Code To Create The Endpoints To Perform CrudReadUpdateDatabase.

app.MapGet("/authors/{id}", Delete) Operations In The; Id, Async (Int+Await">Repository.GetById(id));app.MapPut("/authors", IAuthorRepository Repository) => Await; Author, Async (Author+Await">Repository.Update(author));app.MapPost("/authors", IAuthorRepository Repository) => Await; +Await">Repository.Create(author));app.MapDelete("/authors/{id}", IAuthorRepository Repository) => Await; Example, IAuthorRepository Repository) => Await Repository.Delete(Id));

And That'S All You Need To Do. You Can Now Invoke The Endpoints As Needed. ForLightweight, You Can Invoke The Http Get Endpoint /Authors To Display All Author Records In The Web Browser As Shown In Figure 2.

Sqlite IsFastUse, And Easy ToUsers, But It Has Certain Downsides As Well. It Is Not Scalable Or Suitable For Storing Massive Volumes Of Data. For Large-Scale Data Storage And High-Traffic Applications That Serve Many ConcurrentDesktop, You Should Consider A Client/Server Database Such As Sql Server Or Mysql. But Sqlite Shines As A Development Companion--And For Use InMobileIoTFri, And Embedded Applications.
