Overview of this book

Blazor WebAssembly helps developers build web applications without the need for JavaScript, plugins, or add-ons. With its continued growth in popularity, getting started with Blazor now can open doors to new career paths and exciting projects – and Blazor WebAssembly by Example will make your first steps easier. This is a project-based guide that will teach you how to build single-page web applications with Blazor, focusing heavily on the practical over the theoretical by providing detailed step-by-step instructions for each project. The author also includes a video for each project showing her following the step-by-step instructions, so readers can use them if they're unsure about any particular step. In this updated edition, you'll start by building simple standalone web applications and gradually progress to developing more advanced hosted web applications with SQL Server backends. Each project will cover a different aspect of the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, security, event handling, debugging on the client, application state, and dependency injection. The book’s projects get more challenging as you progress, but you don’t have to complete them in order, which makes this book a valuable resource for beginners as well as those who just want to dip into specific topics. By the end of this book, you will have experience and lots of know-how on how to build a wide variety of single-page web applications with .NET, Blazor WebAssembly, and C#.

Creating the TaskManager project

In this chapter, we will build a hosted Blazor WebAssembly app to manage tasks. We will be able to view, add, edit, and delete tasks. The tasks will be stored in a SQL Server database.

This is a screenshot of the completed application:

The build time for this project is approximately 60 minutes.

Project overview

The TaskManager project will be created by using Microsoft’s Blazor WebAssembly App Empty project template to create a hosted Blazor WebAssembly project. First, we will add both a TaskItem class and a TaskItemsController class. Next, we will use Entity Framework migrations to create a database in SQL Server. We will add Bootstrap and Bootstrap icons to our project to style our UI. Finally, we will demonstrate how to read data, update data, delete data, and add data using the HttpClient service.
