Access modifiers

Access modifiers are an important way of handling the visibility of types and type members by encapsulating code. By using a clear access strategy, the intent of how an assembly and its types should be used can be communicated and enforced. For example, in the FlixOne application, only types that should be accessed directly by the console are marked as public. This means that the console application should have visibility of a limited number of types and methods. These types and methods have been marked as public while types and methods that the console should not have access to, have been marked as internal, private, or protected.
