Adding managed DLL to unity3d

Question

I'm trying to implement the $p library to recognize gestures for spell casting in a game but I'm getting a Unhandled Exception. I'm using the precompile dll I got from their website and its compiled in the .Net 4 framework, so I'm guessing this is where the problem is coming from. Here is the error:

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

Answer 1

You can try changing true to false in your .csproj file. That helps in some cases.
