Location of Microsoft.WindowsAzure.ServiceRuntime

Today while building a new Azure Worker I needed to add a reference to the Microsoft.WindowsAzure.ServiceRuntime, but couldn't find it right away.

I first went to the usual place where you find other Azure references: nuget. But, nope it wasn't there.

I did some poking around and eventually found it in the Add References dialog under Assemblies - Extensions. Hopefully this helps someone else as well.
