How do I check the "App Services / Domain Services" rule?

[max-arshinov]

I want to make sure that Application Services don't call other Application Services and call DomainServices instead.

private IObjectProvider<Class> AppServices = Classes().That().HaveName(@"\S+AppService", true);

//...

Classes().That().Are(AppServices).Should().NotCallAny(
  MethodMembers().That().AreDeclaredIn(AppServices)
);

However, code like this violates this rule

public class MyAppService
{
    public void Smth(){}

    public void SmthElse()
    {
      Smth();
    }
}

Is there a way to exclude "self" from the rule? If not, is there any other workaround?
