Azure websites .NET 4.5.2 availability date

Question

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

It finally happened, .NET 4.5.2 was installed to Azure Websites.

1. David Ebbo, Dev Lead @ Windows Azure Web Sites team twitted on September 5, 2014 the following:

   Azure WebSites is now running .NET Framework 4.5.2 (actually for a month, but we never announced it!)

2. Bilal Alam, Partner Development Manager @ Microsoft Azure Web Workload also confirmed it in a related thread on September 5, 2014:

   .NET 4.5.2 is currently installed on Azure Web Sites. So you can deploy websites which take advantage of 4.5.2 framework features.
