No parameterless constructor defined for this object.

Question

Currently I've got a runtime exception: 'Systen.MissingMethodException : No parameterless constructor defined for this object.

I've googled and came across a lot of people actually not having a default contstructor, though my code actually does, so I don't know where it goes wrong!

My full code can be found here on pastebin since its varely large: http://pastebin.com/RxdKgxSx

Thanks for your help!

Yes: public CursusController() { _agent = new BSCursusBeheerAgent(); } public CursusController(ICursusBeheer agent) { _agent = agent; } — Mittchel, Oct 11 '12 at 08:32

Replace:

public ActionResult Create(UploadViewItem viewItem, HttpPostedFile postedFile)

with:

public ActionResult Create(UploadViewItem viewItem, HttpPostedFileBase postedFile)

ASP.NET MVC works with abstractions over the actual HttpContext objects (HttpContextBase, HttpRequestBase, HttpResponseBase, HttpSessionBase, HttpPostedFileBase, ...).

That's what allows for easier unit testing and mocking those objects.
