SA1600 triggers for `protected internal`

[smaillet]

SA1600 is triggering for methods marked as protected internal.

protected internal void ShowBogusError()
{
}

This is not a public facing method, it is BOTH protected AND internal so no error should appear. (You are at least in good company with this bug as CS1591 has the same problem)

See https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/access-modifiers:
Only code in the same assembly or in a derived class in another assembly can access this type or member.

This behavior seeems to be correct.

@smaillet You would need to use private protected to get what you want.

Only code in the same assembly and in the same class or a derived class can access the type or member.
