Obsolete is an attribute you can place on a class or a method in a class. It will issue a warning or an error on compilation. [System.Obsolete(string argument 1 Boolean argument 2) Argument 1 is a warning statement to display such as Hey stop using this! Use my brand new method instead. Argument 2 is a Boolean that if set to true will issue an error instead of a warning. This argument is optional and it defaults to display a warning instead of an error. Use this if you want to inform developers to use a new replacement method when the old method is left in place to keep old code that might be using the old method from breaking.
