Nice catch @ilivewithian and big sigh to us for letting this one slip.

Sadly we have to keep the typo'd version around with an obsolete attribute:

[Obsolete("Scheduled for removal in 2.0, this method name has a typo")]

This is so that we can maintain a strict backwards compatibility semver wise. We have to do this because we strong name our assemblies but in order to avoid binding redirects we only update the AssemblyFileVersion. This works great but means that code that depends on the typo'd version being in the dll could throw a nasty runtime exceptions if a later fixed 1.x dll ends up being loaded.

Is this something that you can amend this PR with? Also be sure to sign our CLA so that we may pull these bits in: http://www.elasticsearch.org/contributor-agreement/

Yeah, I did wonder if you'd want to keep the old version in some form. I'll update the PR later today.

[ilivewithian]

That's updated, I squashed the change into a single commit, I didn't think you'd want two commits for such a tiny change.

Also, I've signed the CLA.
