Yes, similar questions have been asked before: Azure Websites, Can one deploy .NET 4.5.2 websites
However, the questions are approaching a year old, and the answers are incomplete.
The (cloudy, no pun intended) answer seems to be that 4.5.2 should be supported as of many months ago (though other sources say only 4.5.1 is supported), but my Cloud Deployment Projects don't build (using SDK 2.5) and I hear others complaining of similar issues, but I can't find mention of anyone who has successfully made a 4.5.2 deployment work.
Does anyone have a definitive answer, or has anyone managed to successfully deploy web/worker roles to Azure using .NET Framework 4.5.2?
