To get the most out of this book

I recommend reading the first few chapters to ensure you are up to speed with the basic concepts of Blazor in general. The project we are creating is adapted for real-world use but some parts are left out, such as proper error handing. You should, however, get a good grasp of the building blocks of Blazor.

The book focuses on using Visual Studio 2022; that said, feel free to use whatever version you are comfortable with that supports Blazor.

Software covered in this book	OS requirements
Visual Studio 2022, .NET8	Windows 10 or later, macOS, Linux

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

I would love for you to share your progress while reading this book or in Blazor development in general. Tweet me at @EngstromJimmy.

I hope you have as much fun reading this book as I had writing it.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example; “EditForm will create an EditContext instance as a cascading value so that all the components you put inside of EditForm will access the same EditContext.”

A block of code is set as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.AddRazorPages();
    services.AddServerSideBlazor();
    services.AddSingleton<WeatherForecastService>();
}

Any command-line input or output is written as follows:

dotnet new blazorserver -o BlazorServerSideApp
cd Data

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. For example: “Select Blazor Server App from the search results and press Next.”
