Not sure of the appropriate place to ask this question.
Do you by any chance know the date when .NET 4.5.2 will be generally installed on the Azure Websites?
I seem to have run into a very curious issue - I have recently switch my application over to using HostingEnvironment.QueueBackgroundWorkItem (only available from 4.5.2 onwards). I though I have tested it and it worked on Azure Websites (I'm 99.9999% sure that I have and it worked). I then had a demo scheduled to a potential client - and I hour before the demo I started getting the method not found exception on the pages that were using that API call.
It is currently running on a shared tier. Are all of the Azure website servers of the same patch level or could it have happened that the website was moved to a different server during one of the redeployments and that server had a different patch level? I just need to understand the behaviour - in order to avoid running into this issue in the future!
Thanks, Nick
