Cant use FirstDispositionNameOrDefault after asp.net mvc4 WebApi beta Upgrade

I have just upgraded from WebApi beta to the latest WebApi packages from NuGet. The visual studio project I am using targets .NET 4.0 and not 4.5.

I have been able to resolve all issues but one. I am uploading files using Multipart Form via the following code:

        // Verify that this is an HTML Form file upload request
        if (!Request.Content.IsMimeMultipartContent("form-data"))
        {
            throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
        }

        var task = Request.Content.ReadAsMultipartAsync();

        var dateField = task.Result.FirstDispositionNameOrDefault("expireby");

        if (dateField == null)
        {
            return this.SendResponse(HttpStatusCode.BadRequest, ":dateNotFound:");
        }

        var dateFieldValue = dateField.ReadAsStringAsync().Result;

        if (!DateTime.TryParse(dateFieldValue, out expireBy))
        {
            return this.SendResponse(HttpStatusCode.BadRequest, ":invalidDateFormat:");
        }

The method FirstDispositionNameOrDefault is not getting compiled anymore and I get the following error:

'System.Net.Http.MultipartMemoryStreamProvider' does not contain a definition for 'FirstDispositionNameOrDefault' and no extension method 'FirstDispositionNameOrDefault' accepting a first argument of type 'System.Net.Http.MultipartMemoryStreamProvider' could be found (are you missing a using directive or an assembly reference?)

Google did not return any relevant results. Can someone provide insight into this issue?

It is true that the API you used in your codes was changed after Beta. It was designed to address following issue: http://aspnetwebstack.codeplex.com/workitem/53

And here's the change set http://aspnetwebstack.codeplex.com/SourceControl/changeset/8fda60945d49

If some additional instruction is helpful, here it is http://www.asp.net/web-api/overview/working-with-http/sending-html-form-data,-part-2
