Directory.EnumerateFiles() is missing from the wrapper


I originally posted this at this github project (which publishes a newer version of this), but received no response, so re-posting here.

I was playing around with this and looks pretty good. However while trying to convert one of my methods to use DirectoryWrap, I realized that DirectoryWrap doesn't implement EnumerateFiles method.
Could it be that I am doing some obvious mistake?
I also tried new DirectoryInfoWrap(path).EnumerateFiles and that too is missing.
I am using .Net 4.5.
