MVC: no views found, no locations were searched. Now why is that?

The image of a login page (clickable image): http://i.snag.gy/sHPyQ.jpg

Is it seems (though the debug viewer), the ViewEngines are both (razor+webforms, im using the first) there, in the ViewEngines collection, and them both can find the views (manually) and display them, also tried manually.

So why is that they cannot do it on their own? This is simply an action method, nothing more:

public ViewResult Login()
{
    return View();
}

Major Update

I have overridden the OnResultExecuting method:

protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
    if (filterContext.Result is ViewResult)
    {
        if (((ViewResult)filterContext.Result).ViewEngineCollection.Count == 0)
        {
            ((ViewResult)filterContext.Result).ViewEngineCollection.Add(new RazorViewEngine());
        }
    }

    base.OnResultExecuting(filterContext);
}

And it turned out that every time and every view I do now need to add new IViewEngine to a ViewResult. Now why is that so? Even if the ViewEngines.Engines collection is not empty?

Minor update.

The ViewEngineCollection stopped being empty at some point of idling.

The ViewEngineCollection stopped being empty at some point of idling.

This only might refer to some ASP.NET caching of old assemblies which was not for some reason updated by the new ones. This happens from time to time, and I have to clear the cache in order for some new code to work.

Do you have a master page defined?

If you have a _ViewStart.chstml file in the root of your solution then it is possible the engine is trying to load a master page to combine with your view.

To skip the master page tell your view to not use a master page. Add the following to the View

@{
    Layout = null;
}

or make sure that the master page referenced in the _viewStart.cshtml file exists.

You may not have a correct ViewEngines configured (or none).

Try adding to view engines manually to identify if there is a configuration error somewhere.

Add something like this to Application_Start() method of Global.asax.

protected void Application_Start()
{
   ViewEngines.Engines.Clear();
   ViewEngines.Engines.Add(new RazorViewEngine());
   // Other code
}

This should initialise the Razor view engine, and if as a result mvc starts searching locations, you have somehow turned off razor in the configuration.
