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.

Hot reload (almost the real thing)

With .NET 5, we got the ability to reload our Blazor site when we make changes to a code file. Users have asked for hot reload and Microsoft is aiming to release hot reload in the .NET 6 timeframe.

To set this up, do the following:

  1. In Visual Studio, select the Tools menu and then Options.
  2. Select Projects and Solutions and then ASP.NET Core.
  3. In the right box under the General heading, change the value of the Auto build and refresh option to Auto build and refresh browser after saving the changes.
  4. Right-click on MyBlogServerSide and select Set as Startup project.
  5. Now run the project by pressing Ctrl + F5 (it only works without debugging).
  6. In the web browser, bring up the counter page by adding /counter to the URL.
  7. Make a change to the Pages/Counter.razor file and click Save.

    Our web browser should now reload, and the change will be shown.

This also works from the command line by running the following command...
