Now that .NET 4.5 and Visual Studio 2012 has RTM, is there a way to use it on Windows Azure yet? I'm aware of the hacks people used for .NET 4.5 RC, but I'm looking for a clean solution.
If it isn't possible yet, does anyone know when the tools, etc. will be updated to support it?

NET Framework 4.5. 2, 4.6, and 4.61 retired on April 26, 2022. These specific releases were previously signed using Secure Hash Algorithm (SHA-1) certificates. This algorithm is no longer secure.
Download .NET Framework 4.5. Free official downloads.
If you're on Windows 7 and haven't yet installed Service Pack 1, you need to do so before installing the . NET Framework. . NET Framework 4.5 is supported on the Windows Preinstallation Environment (Windows PE).
NET, go to Control Panel -> Programs and Features -> Turn Windows features on or off. This will open the Add Roles and Features Wizard as part of Server Manager. You can modify the . NET version during the Features step of the Wizard.
At the moment there is no way to use .NET 4.5 out-of-the-box on Windows Azure. What you can do is use the Windows Azure Bootstrapper to download .NET 4.5 and install it:
bootstrapper.exe -get http://download.microsoft.com/download/B/A/4/BA4A7E71-2906-4B2D-A0E1-80CF16844F5F/dotNetFx45_Full_setup.exe -lr $lr(temp) -run $lr(temp)\dotNetFx45_Full_setup.exe -args /q /norestart -block Besides that I would keep an eye out for updates related to .NET 4.5 on the Guest OS Releases page.
Update 3-sep-2012: Have you seen this message: "Beginning October 3rd 2012, Windows Azure will no longer support Cloud Services (Hosted Services) deployed on Guest OS versions 2.9 or older and 1.17 or older.". This might indicate a change in Guest OS versions on October 3rd (maybe with support for .NET 4.5)...
Update 18-sep-2012: Confirmation from Scott Guthrie that .NET 4.5 support is due for October 2012.
