Conventions used

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

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The input() method is used to get an input from the user."

A block of code is set as follows:

private int FindError(string string1, string string2)
{
int error = 0;
for (int i = 0; i < string1.Length; i++)
error += Math.Abs((int)string1[i] - (int)string2[i]);
return error;
}

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

Install-Package App.Metrics
Install-Pacakge App.Metrics.AspnetCore.Mvc

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: "If you need something different, click on the DOWNLOADS link in the header for all possible downloads: "
