ASP.NET Core 2 and Angular 5

Overview of this book

Become fluent in both frontend and backend web development by combining the impressive capabilities of ASP.NET Core 2 and Angular 5 from project setup right through the deployment phase. Full-stack web development means being able to work on both the frontend and backend portions of an application. The frontend is the part that users will see or interact with, while the backend is the underlying engine, that handles the logical flow: server configuration, data storage and retrieval, database interactions, user authentication, and more. Use the ASP.NET Core MVC framework to implement the backend with API calls and server-side routing. Learn how to put the frontend together using top-notch Angular 5 features such as two-way binding, Observables, and Dependency Injection, build the Data Model with Entity Framework Core, style the frontend with CSS/LESS for a responsive and mobile-friendly UI, handle user input with Forms and Validators, explore different authentication techniques, including the support for third-party OAuth2 providers such as Facebook, and deploy the application using Windows Server, SQL Server, and the IIS/Kestrel reverse proxy.

Setting up the DbContext


To interact with data as objects/entity classes, Entity Framework Core uses the Microsoft.EntityFrameworkCore.DbContext class, also called DbContext or simply Context. This class is in charge of all the entity objects during runtime, including populating them with data from the Database, keeping track of changes, and persisting them to the Database during CRUD operations.

We can easily create our very own DbContext class for our project--which we will call ApplicationDbContext--by doing the following:

  1. From Solution Explorer, right-click on the /Data/ folder we created a while ago and add a new ApplicationDbContext.cs class file.
  2. Fill it up with the following code:
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Metadata;

namespace TestMakerFreeWebApp.Data
{
    public class ApplicationDbContext : DbContext
    {
        #region Constructor
        public ApplicationDbContext(DbContextOptions...
