17 Building User Interfaces Using Blazor

This chapter is about using Blazor to build user interfaces. I will describe the different flavors of Blazor and their pros and cons.

You will learn how to build Blazor components that can execute their code on the web server or in the web browser. When hosted with Blazor Server, it uses SignalR to communicate needed updates to the user interface in the browser. When hosted with Blazor WebAssembly, the components execute their code in the client and must make HTTP calls to interact with the server.

In this chapter, we will cover the following topics:

Understanding Blazor
Comparing Blazor project templates
Building components using Blazor Server
Abstracting a service for a Blazor component
Building components ...
