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: “ One of them is the Share option. We have set it to FileShare.Delete "

A block of code is set as follows:

using var serialPort = new SerialPort(
    "COM3",
    9600,
    Parity.None,
    8,
    StopBits.One);
serialPort.Open();
try
{
    serialPort.Write([42],0, 1);
}
finally
{
    serialPort.Close();
}

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

docker tag image13workerfordocker:dev localhost:5000/image13workerfordocker:dev

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: “Compact object representations: Sometimes, you can save some memory by smartly combining data into other data structures”.
