PostSharp and EntityFramework 5 do not work together - postsharp

Question

I am trying to upgrade my MVC 3 project to MVC 4 and while I install EF5, the PostSharp do not let compile the project. I get error below. Spend several hours trying to resolve the problem without any luck. The PostSharp refers to entityframework, version=4.3.1.0 but there is no such version in my project, I have left only 5.0 version. Even searching all project files using external text editor do not give any search result for "4.3.1.0". So I have no idea where PostSharp picks it up. Any suggestions how to solve the problem?
Error 2 Unhandled exception (2.1.7.28, 32 bit, CLR 4.0, Release): PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'entityframework, version=4.3.1.0, culture=neutral, publickeytoken=b77a5c561934e089'. [Version mismatch]

I think you may have some assembly binding policies in app.config, which makes the CLR look for v5.0 instead of v4.3.1. PostSharp does not support binding policies in app.config, but only system-wide ones (like the ones redirecting .NET 1.0 to 2.0).
Binding policies in app.config are supported in PostSharp 3, but at the time of writing this feature has not been documented, and PostSharp 3 is still CTP.
The only solution for the moment is to make sure that all components and references of your projects have references (are linked) to v5.0, so no binding policy is necessary.
