Answer 1

You may be using an assembly that couldn't be loaded correctly. For checking which one may fail I would recommend you this utility: http://www.dependencywalker.com/

It scans your app for dependencies and highlight the ones that were not found. In my case was a C++ assembly that was missing.

Answer 2

From what I know the error code means, that an assembly couldn't be loaded. It is corrupt or not avaliable.

Clear the \bin folder of your project and the AppData (Temp) folder (located at C:\Users\your_username\AppData\Local\Temp\Temporary ASP.NET) and see if the error still happens.
