Variable expansion in PowerShell In the above case, PowerShell processes$MyVar2because it was enclosed by a double-quoted string. Double quotes make PowerShell parse for text (the variable) preceded by a dollar sign and substitutes the variable name the corresponding value. Real World Scenario N...
