Class vs. Public Class

Question

What is the difference between:

namespace Library{
    class File{
        //code inside it
   }
}

and:

namespace Library{
         


        

Answer 1

Without specifying public the class is implicitly internal. This means that the class is only visible inside the same assembly. When you specify public, the class is visible outside the assembly.

It is also allowed to specify the internal modifier explicitly:

internal class Foo {}
