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. Here is an example: "By doing this in _Layout.cshtml, we ensure that this functionality is common across all the pages."

A block of code is set as follows:

# include<stdio.h>

int hello()
{
  return 15;
}

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

else
       {
           app.UseExceptionHandler("/Home/Error");
       }
       app.UseStaticFiles();
       app.UseMvc(routes =>
       {

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

mcs -out:helloNative.exe InteropWithNativeSO.cs

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: "Enter Display Name and Contact Email, and click on the Create App ID button."
