After watching the key note address from Scott Gu at AspConf I got excited about trying the Windows Azure Web sites with MVC4. I tried deploying an existing MVC application after re-configuring it to target .NET framework 4.0 instead of 4.5 and got the following error.
Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Since I had already added several NuGet packages I thought it might have something to do with Ninject so I created a new MVC project targeting the .NET 4.0 framework with no NuGet packages and deployed to Windows Azure using the Visual Studio 2012 RC Publish option (right-clicking the Web project) and I still get this error.
Does anyone know what's going on or how to fix this issue? Thanks in advance.

In the Publish Web Application wizard if I select Settings | Remove additional files at destination this problem went away.
