Import LibGaze dll file in Unity3D

Question

I want to import the dll file of LibGaze in Unity.

I put the dll in the "Assets/Plugins" folder. I managed to add that dll as reference in mono editor, the namespace and classes seem to be recognized by mono editor without problem (when I type class names in the dll, they are in the list of auto-completion).

But when I go back to unity main window, it says: "error CS0246: The type or namespace name `libGaze' could not be found. Are you missing a using directive or an assembly reference?" When I double click this error message, it points me to the using statement of LibGaze library in the script.

You need Unity Pro to use (import) Dll's, are you using Unity Free or Unity Pro? — Johan, Mar 02 '15 at 09:56
Don't use unity tag for questions related to Unity3d game engine. — Max Yankov, Mar 02 '15 at 21:36

Found this question which seems to explain my problem : Getting "type or namespace name could not be found" but everything seems ok?

Since unity only support .Net 2.0 and the dll file is compiled with a higher version of .Net, unity cant correctly import it.

Tested with the new unity5, mono editor still only supports .Net 2.0
