 Deploying an FDD has a number of advantages:

  A common use of internal access is in component-based development because it enables a group of components to cooperate in a private manner without being exposed to the rest of the application code. For example, a framework for building graphical user interfaces could provide `Control` and `Form` classes that cooperate by using members with internal access. Since these members are internal, they are not exposed to code that is using the framework.

 The .NET binary format is based on the Windows [PE file](https://en.wikipedia.org/wiki/Portable_Executable) format. In fact, .NET class libraries are conformant Windows PEs, and appear on first glance to be Windows dynamic link libraries (DLLs) or application executables (EXEs). This is a very useful characteristic on Windows, where they can masquerade as native executable binaries and get some of the same treatment (for example, OS load, PE tools).
