“File does not exist” in ASP.NET MVC

I just started getting the “File does not exist” exception. The exception occurs after I press the Run button in visual studio. Also as far as I can tell, none of my code is hit. The code part that should hit is 

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

But the breakpoint in that code is never hit. .. I followed How to solve exception "File does not exist"? and System.Web.HttpException File does not exist - Page loads just fine (ASP.NET) and wrote the following code:

void Application_Error(object sender, EventArgs e)
{
    Exception ex = Server.GetLastError();

    if (ex.Message == "File does not exist.")
    {
        var foo = Request.RawUrl;
        var newEx = new Exception(string.Format("{0} {1}", ex.Message, HttpContext.Current.Request.Url.ToString()), ex);   
    }
}

Now when I run and hit this code, foo is set to "/" and newEX is "File does not exist. http://localhost:63456/"

Any ideas?

Here is the stack trace:

Also typing Server.GetLastError().StackTrace.ToString() in the Imediate Window gives:

So what had happened was this: I had the following Controller method:

    public ActionResult SearchTitle(string path)
    {
        //lots of code here
        return Index();
    }

and the following route:

        routes.MapRoute("SearchTitle", "{*path}",
            new { controller = "Home", action = "SearchTitle", path = UrlParameter.Optional });

Since I was not using SearchTitle, I quickly deleted the method and the associated routing. This was the cause of the error.

The solution was to keep the Controller deleted, but change the routing to

        routes.MapRoute("Default", "{*path}",
            new { controller = "Home", action = "Index", path = UrlParameter.Optional });

Note: There was never any files missing

There are instances where visual studio will not hit a valid break point. Include system.diagnostics namespace and use debugger.break() to force a breakpoint. Remove from your code when your problem has been identified.
