c# - CreateServiceHost method is protected while MSDN says it's public

Question

Reading an MSDN tutorial on Extending Hosting Using ServiceHostFactory, there is an example of overriding a CreateServiceHost function:

public class DerivedFactory : ServiceHostFactory
{
   public override ServiceHost CreateServiceHost( Type t, Uri[] baseAddresses )
   {
      return new DerivedHost( t, baseAddresses )
   }
}

However, when we look at the actual definition of the class, the CreateServiceHost method is protected:

protected virtual ServiceHost CreateServiceHost(
    Type serviceType,
    Uri[] baseAddresses
)

My question is, what should I override? Is MSDN example wrong?

Answer 1

キーワードは、そのprotectedクラスまたはそのクラスのサブクラス内からのみアクセスできることを意味します。から継承したい場合ServiceHostFactory、問題はないはずです。オーバーライドすることもできますCreateServiceHost。
