Web Development with Blazor

By: Jimmy Engström

Overview of this book

Blazor is an essential tool if you want to build interactive web apps without JS, but it comes with its own learning curve. Web Development with Blazor will help you overcome most common challenges developers face when getting started with Blazor and teach you the best coding practices. You’ll start by learning how to leverage the power of Blazor and explore the full capabilities of both Blazor Server and Blazor WebAssembly. Then you’ll move on to the practical part, which is centred around a sample project – a blog engine. This is where you’ll apply all your newfound knowledge about creating Blazor Server and Blazor WebAssembly projects, the inner working of Razor syntax, and validating forms, as well as creating your own components. You’ll learn all the key concepts involved in web development with Blazor, which you’ll also be able to put into practice straight away. By showing you how all the components work together practically, this book will help you avoid some of the common roadblocks that novice Blazor developers face and inspire you to start experimenting with Blazor on your other projects. When you reach the end of this Blazor book, you'll have gained the confidence you need to create and deploy production-ready Blazor applications.

Debugging Blazor Server

If you have debugged any type of .NET application in the past, you will feel right at home. If you haven't, don't worry – we will go through it. Debugging Blazor Server is just as we might expect and is the best debugging experience of the three different types we will cover.

I usually keep my Razor pages in a shared library and while building my project, I use Blazor Server for two reasons – first, it's a bit faster to run the project, and second, the debugging experience is better.

Let's give it a try!

  1. Right-click on MyBlogServerSide and click Set As Startup project.
  2. Press F5 to start the project (this time with debugging).
  3. Using the web browser, navigate to https://localhost:5001/throwexception (the port number may vary).
  4. Press F12 to show the web browser developer tools.
  5. In the developer tools, click Console.
  6. Click the Throw exception button on our page.

    At this point, Visual Studio should...
