You can define a namespace at the top-level of a source file or you can define a namespace within another namespace. When you define a namespace within another namespace, you can refer to the inner namespace using a dotted (outer.inner) syntax.
In the example below, we have a Dog class defined within the top-level DogLibrary namespace. The full name for this type is DogLibrary.Dog. We also define a Utility namespace within the DogLibrary namespace, and a DogLoggerclass whose full name is then DogLibrary.Utility.DogLogger.
