Your hosting provider does not yet support ASP.NET 4.5

I am following along the tutorial

And when I start the publish routine Azure tells me it does not support 4.5...  Really! ?

I am using a freshly installed version of VS Ultimate 2012 RC.

Is this what Scott was running into in his demos?

Any help would be appreciated.

Thanks, Terrence

Edit:  I will leave this post here for those who blow it like I did.

Woops! Guess I wasn't following along too closely.  I missed this tiney little detail.

Change the .NET Framework drop-down list from .NET Framework 4.5 to .NET Framework 4. (As this tutorial is being written, Windows Azure Web Sites do not support ASP.NET 4.5.)

As far as i know, currently Windows Azure application does not support .NET Framework 4.5 yet, like the link you shared above, we can create could application in VS 2010 and 2012 RC, if you select the .NET Framework 4.5, the cloud project template is null, but i guess Azure SDK will supports 4.5 in the future.

Hope this helps.

I answered my own question on the original post, but left it up on the forums so others could benefit from it.  There is no way to mark my original post as the answer.

You can achieve get the 4.5 on role machines by adding a start up task to it. so that you could leverage 4.5 features on azure. It is a little pain as of now, but you could achieve it. Here is the blog you can refer to.

Make sure that you are doing this on your own risk as it is offically not supported by azure team. For you experience or testing purpose you could use .net 4.5 with the steps mentioned in the blog.

Hope it helps you atleast to aware that there are some workarounds to make .net 4.5 work on azure.
