Since updating to VS2013, we receive this error when running our (MCV4) web app:
The controller for path \'/9ac086a69364466a841e03e001f946fd/arterySignalR/pi
If you would like the benefit of Browser Link but don't want the missing controller path exceptions, you can add an ignore regex to your route collection. This is what I did:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
#if DEBUG
routes.IgnoreRoute("{*browserlink}", new { browserlink = @".*/arterySignalR/ping" });
#endif
//...
}
The regex technique is courtesy of this Phil Haack post.
