I'm using Entity Framework 4.2 June 2011 CTP in a small web application (ASP.NET MVC 3) because it supports enums.
I tried to deploy it using web deploy and I get the following error :
The application pool that you are trying to use has the 'managedRuntimeVersion' property set to 'v4.0'. This application requires 'v4.2'.
How to create an application pool running on .NET 4.2 ?
Edit: The web application does work with a 4.0 app pool so the real question is how to disable the app pool runtime version check when using Visual Studio Publish option ?

I found the solution here: http://connect.microsoft.com/VisualStudio/feedback/details/526963/unable-to-correctly-set-managedruntimeversion-in-msdeploy-package
Add this to the web .csproj file in the initial <PropertyGroup> section:
<IgnoreDeployManagedRuntimeVersion>True</IgnoreDeployManagedRuntimeVersion>

There is no .Net framework 4.2 out there, i would imagine the .net 4 sp1 is missing or you are not including all needed references. try installing sp1 on the server.
