How can I use .NET framework 4.5 in Unity 5

I'm working with unity3D 5. And I wanna import external my KinectDB.dll (includes my sql server db functions with entityframework. And it was complied with .NET 4.5 framework) class library to unity. But unity console gives me an error like below. I searched for this problem many hours. But I can't reach to complete solution. How can I solve this? What are your advices? Thanks in advance.

Hint : I created an example project with .NET 3.5 framework. And I import it to unity. Unity doesnt give me an error in this case.

  Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

You can only wait till Unity updates its bundled Mono to 4.x. It is already on their roadmap. With Microsoft licenses Mono runtime from LGPL to MIT and Unity joined .NET Foundation, it is likely that such a platform upgrade might come sooner.

Yeah. It all starts with reading the documentation - and realizing that Unity uses a quite outdated version of .NET. You CAN NOT use 4.5 libraries in Unity. What you CAN do is run them in a separate program and communicate with this program via network etc. - but that is a LOT of work.

Once in the future Unity will upgrade. But they have not yet.
