Signs on the Sand

I've seen some people talking and some leaving comments that newly introduced XPathNavigator.SelectSingleNode() method is actually a wrapper around XPathNavigator.Select and so it provides no performance benefits. This is both true and false. It's true that you won't get any performance boost from moving to XPathNavigator.SelectSingleNode() method, because it's really just a wrapper around XPathNavigator.Select() returning first selected node. But that's also false that there is something wrong with it. No performance boost because XPathNavigator.Select() is efficient itself and never selects all nodes, returning instead XPathNodeIterator, which actually selects nodes once its MoveNext() method is called. So there is no perf difference, both are very fast and XPathNavigator.SelectSingleNode() method is mostly just about code elegance and convenience for a coder.
