MEF 2.0 (Nuget version) is not compatible with .NET 4.5.2

If you try to create a ContainerConfiguration in .NET 4.5.2, you will likely get the following error message:

"The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'."

Please, upgrade the nuget package.
