The difference between `+private+` and `+protected+` visibility is that child classes can see and use `+protected+` members, but they cannot see `+private+` ones. Since a `+sealed+` class cannot have children, marking its members `+protected+` is confusingly pointless.

== Noncompliant Code Example

----
public sealed class MySealedClass 
{
    protected string name = "Fred";  // Noncompliant
    protected void SetName(string name) // Noncompliant
    {
        // ...
    }
}
----

== Compliant Solution

----
public sealed class MySealedClass 
{
    private string name = "Fred";
    public void SetName(string name)
    {
        // ...
    }
}
