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: “Let us use the IEnumerable interface to query the database.”

A block of code is set as follows:

using (var serviceScope = app.Services.CreateScope()){
    var services = serviceScope.ServiceProvider;
    // Ensure the database is created.
    var dbContext = services.GetRequiredService<AppDbContext>();
    dbContext.Database.EnsureCreated();}

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

cd GrpcDemo.Client dotnet add GrpcDemo.Client.csproj package Grpc.Net.Client

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click the Continue button.”
