Fixes #101

When contentType of AJAX request is set to 'application/json; charset=utf-8', the type of valueProviderResult.RawValue is not an array.
I don't quite see how this works, you changed the version here, but the hint path is still pointing to the dll in referenced assemblies, which is not 4.0.

Ideally, all the mvc references would be removed replaced with references from nuget.
