Why elements defined in a namespace only can be explicitly declared as public?

Question

program sample:
https://code.sololearn.com/crUxoTHcA4Nx/#cs

If i change class program as private, there's error message:

"..\Playground\(12,17): error CS1527: Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal"

Answer 1

Making a variable protected means that subclasses have access to it. A namespace is not a class though and you can't "subclass" it, so that makes no sense of course.

I can see why private seems like it should be an option, but then again, in C# you can spread your namespace over multiple files. So you can always get yourself access to private namespace variables if you need them, by adding a public method to the namespace that returns the private variable.

EDIT: and things get tricky across assembly boundaries. I can't imagine what a non-internal, private variable as seen from a different assembly would even do (or why you'd need that)!
