Summary

As a user, I want to see what the impact of some of the commands is going to be. This helps to provide messages even before the command is actually executed. With the rise of dsc.exe, this allows implementing the -WhatIf operation.

Scenario: Install a language

Take for example the Install-Language command. Even though you could use $allLangues = [System.Globalization.CultureInfo]::GetCultures("AllCultures") to list out all languages and pass it to Install-Language, what if a user appends the -WhatIf switch. It can provide information early on stating:

• The language was not found
• Attempting to install the language
• Language already exist
