There's no such thing as "package visibility" in C#,
but there is "assembly visibility", which limits the
definition to the DLL in which it resides.  The keyword
is "internal".  "protected internal" can be used to
restrict things further so that only subclasses in
the same assembly can see the definition.

C# cases do NOT fall through, and the compiler will give
an error if the case doesn't end with some kind of jump
instruction (usually "break").  If you need to fall through,
then use "goto case N", where "N" is the label on the
next case.  "goto default" is used when the next case
is the default case.

Yes, it's stupid, but it's too late to change it now. :-(
