title: Error "Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal"
body: <p>I tried to make a class as private and got this Error <strong>"Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal"</strong></p>
  
  <p>I got its meaning but I want to ask why this is not allowed? Are all access modifires not applicable on Class? Why I can't make a class private, protected or protected internal?</p>
