'Inheritance security rules violated while overriding member' with EntLib 5.0 and .NET 4

Question

I'm using EntLib 5.0 with .NET 4. It was working, but now I've used ILMerge in order to merge all the dlls in one redistributable .dll. Everything works but EntLib5. When I try to get a logger, I get this exception:

System.TypeLoadException was unhandled by user code
  Message=Inheritance security rules violated while overriding member: 'Microsoft.Practices.Unity.ResolutionFailedException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.
  Source=My.Common.Compacted
  TypeName=Microsoft.Practices.Unity.ResolutionFailedException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)

  InnerException: 

I've read here in SO that that exception comes from .NET4 because now it's more strict in terms of coding security, but what can I do? download the EntLib 5 source code and fix it myself?

Is there any way to disable that check?

I've merged the files in this order, maybe it's the wrong order:

"$(TargetDir)My.Common.dll" 
"$(TargetDir)Microsoft.Practices.ServiceLocation.dll" 
"$(TargetDir)Microsoft.Practices.Unity.dll" 
"$(TargetDir)Microsoft.Practices.Unity.Interception.dll" 
"$(TargetDir)Microsoft.Practices.EnterpriseLibrary.Common.dll" 
"$(TargetDir)Microsoft.Practices.EnterpriseLibrary.Logging.dll"

Cheers.
