问题 I'm getting error below when I debug my ASP.NET MVC app. Any thoughts on how I could solve this? Any idea how the problem would have occurred in the first place?

I managed to build a DLL using gcc under Windows : #include<stdio.h> int add(int a,int b) { return(a+b); } I try now to use it through my dll. After reading some posts, especially this one, I couldn't manage to make this work: Reference a binary-component to js-ctypes Each time I try ctypes.open, I have the error message: couldn't load the library . However, the DLL path is correct. Here is the JS code: Components.utils

问题 Tl;dr version: I am stuck with the exception: System.IO.FileLoadException : Could not load file or assembly 'DotNetOpenAuth.AspNet, Version 4. 0 .0.0 ... A bit dismayed that msft used so many static classes and methods for auth in the new MVC4 project template.
