AspMvcPartialViewAttribute not working properly

I have setup the following annotation:
//
//Rsharper annotations
//
[assembly: AspMvcPartialViewLocationFormat(@"~/Views/NexPortHelp/{1}/{0}.cshtml")]

And the following custom ViewEngine

/// <summary>
    /// Implementation of the razor view engine allowing custom behavior overrides
    /// </summary>
    public class NexportViewEngine : RazorViewEngine
    {
        private static string[] NewPartialViewFormats = new[]
        {
            @"~/Views/NexPortHelp/{1}/{0}.cshtml"
        };

        public NexportViewEngine()
        {
            //Allow custom paths for partial views
            base.PartialViewLocationFormats = base.PartialViewLocationFormats.Union(NewPartialViewFormats).ToArray();
        }
    }

The intellisense for the NexportHelp folder now shows up when I use the AspMvcPartialView Attributwe on parameters BUT it shows up with the full path (C:\..fullpath to view).

Any help would be great
