It seems that microsoft have failed to keep the emulator in line with the storage account api.
I am trying to use the nuget package WindowsAzure.Storage.18.104.22.168
I have an attempt at creating a powershell script to query table storage.
It can be found on https://github.com/chriseyre2000/Powershell/tree/master/Azure
I plan on using the previous version windowsazure.storage 22.214.171.124 to see if that works against the emulator.
When working in Azure you need to keep up with versions before they are disabled, but if you go too far then it will hurt.
