Conventions used

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

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Open the file Startup.cs of the project you just created.”

A block of code is set as follows:

public Task StopAsync(CancellationToken cancellationToken)
{
    logger.LogInformation(“Hosted service stopping”);
    return Task.CompletedTask;
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

app.UseEndpoints(endpoints =>
{
    endpoints.MapGet(“/”, async context =>
    {
        await context.Response.WriteAsync(
            “Hello World!”);
    });
    endpoints.MapAppStatus(“/status”, “Status”);
});

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

dotnet new web -n SampleProject -o SampleProject
cd SampleProject
code .

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “Select System info from the Administration panel.”
