If in assembly (and namespace) A I have: protected internal abstract bool IsHierarchical { get; } and in assembly (and namespace) B I implement it as: protected override bool IsHierarchical { get { return true; }} then I get a red underline on my "get" with a resharper warning "Cannot change access modifiers when overriding 'PROTECTED_OR_INTERNAL' inherited member 'IsHierarchical.get'. If I change my implementation to say "protected internal override", as the warning seems to suggest, I get a compiler error. I think the resharper warning is wrong. Thanks! -Rich
