C# 7 and .NET Core: Modern Cross-Platform Development - Second Edition

Building console applications

Console applications are text-based and are run at the command prompt. They typically perform simple tasks that need to be scripted, such as compiling a file or encrypting a section of a configuration file. They can have arguments passed to them to control their behavior for example, to encrypt the database connection strings section in a Web.config file, use the following command line:

aspnet_regiis -pdf "connectionStrings" "c:\mywebsite"
