Sitecore: Error upon adding a rendering to a Placeholder

View Error Screenshot I am working on the exercise project and cannot seem to add a rendering to a placeholder using the Experience Editor. The site gives a javascript error(albeit, a very vague one) with the following error in the logs:

Nested Exception

Exception: Sitecore.Mvc.Diagnostics.ExceptionWrapper
Message: The controller for path '/' was not found or does not implement IContro
ller.

   at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext re
questContext, String controllerName)
   at Sitecore.Mvc.Controllers.SitecoreControllerFactory.CreateController(Reques
tContext requestContext, String controllerName)

I have searched everywhere with no solution. Has anyone else experienced this issue?

EDIT

Model:

 public class FeaturedEvents
    {

        public FeaturedEvents()
        {

        }
        public HtmlString Heading { get; set; }
        public HtmlString Intro { get; set; }

        public HtmlString EventImage  { get; set; }
    }

Controller:

   public class FeaturedEventController : Controller
    {

        public ActionResult Index()
        {
            return View(CreateModel());
        }

        private static FeaturedEvents CreateModel()
        {
            var item = RenderingContext.Current.Rendering.Item;
            var FeaturedEvent = new FeaturedEvents()
            {
                Heading = new HtmlString(FieldRenderer.Render(item, "ContentHeading")),
                EventImage = new HtmlString(FieldRenderer.Render(item, "Event Image", "mw=400")),
                Intro = new HtmlString(FieldRenderer.Render(item, "ContentIntro"))
            };

            return FeaturedEvent;


        }
    }

Route

I am using the default route. I wasn't instructed to change it.

I have created a controller rendering and linked the placeholders as well. But, as soon as I select the rendering for the placeholder in the Experience Editor, it gives me the "An Error occurred" pop up dialog.

Trace Server Error in '/' Application.

The controller for path '/' was not found or does not implement IController.

Can you please provide the code snippet for the controller and also the route you are using? - Hishaam Namooya
Updated the question good Sir :) - Muhammad Arqum
events.tac.local.Controllers.FeaturedEventController, events.tac.local. I am using fully qualified name here now. I tried the normal way before which is, just use the controller name (minus the "Controller") and Index in the view. - Muhammad Arqum
Please see answer below - Hishaam Namooya

I have reproduced the issue on a local instance. I have created the controller rendering in Sitecore as shown below

enter image description here

and update the code accordingly. I have then try to add the rendering on the Experience Editor. This eventually caused the same error.

Solution

The issue was because the dll referencing the Controller was not in the bin folder. So, please make sure that the assembly referencing the Controller is in the bin folder.

Also, even if the dll is in the bin folder, it may be that it is not being overwritten with the new one. You may try to copy and paste the dll into the bin folder.
