Now that issue #63 is resolved, I can create a simple console application, add the NLua NuGet package, change the platform target to x64 and compile it. Yay!

The problem I'm having now is with my real application, with is a 32-bit XNA project. The XNA libraries are 32-bit only, so I don't have the option to change the platform target. Trying to run my program after adding the package (and the line var lua = new Lua()) throws an exception:

BadImageFormatException: An attempt was made to load a program with an incorrect format.
