I'm getting a BadImageFormatException when trying to load the LibGit2Sharp library in a csx file.

I'm running ScriptCS version 0.13 on Windows 8.1 x64 - see https://gist.github.com/sbedford/472d9fa63a8304ce0b2f for a reproduction.

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'git2-e0902fb.dll' or one of its dependencies. The module was expected to contain an assembly manifest. ---> System.BadImageFormatException: Could not load file or assembly 'git2-e0902fb.dll' or one of its dependencies. The module was
expected to contain an assembly manifest.
