I'm trying to use the TableStorageSessionStateProvider from the Azure training kit. I can use the example without problems but when I use it in my web app, I get this exception:
System.Data.Services.Client.DataServiceRequestException occurred
Message=An error occurred while processing this request.

I've tried this, but no luck so far.I've also seen null reference exceptions happening, so I guess that the TableStorageSessionStateProvider it's not behaving like the InProc one, so maybe I have to check how sessions are being used in the application. But, what could be the problem ?
EDIT: Well, I've find out that the example in the Azure training kit also fails if you only use the TableStorageSessionStateProvider with the same exception. You just have to comment the other providers:
