Hi Viv,

With some help of my colleague I was able to solve that problem. My js code is now

 if ($scope.attachments.body.rows.length >0 )
                    {
                        var files = [];
                        $.each($scope.attachments.body.rows, function (index, fileInfo) {                            
                            files.push(fileInfo.content);
                        });
                        Upload.upload({
                            url: 'api/EMessage/UploadFilesWithData',
                            multiple: true,
                            data: {
                                files: files,
                                data: Upload.json(eMessage)
                            }
                        }).then(function (response) {
                            //$timeout(function () {
                            //    $scope.result = response.data;
                            //});
                            var alertMessage = resourceFactory.getResource('Messages', 'sendingProcessCompleted');
                            toastr.clear();
                            toastr.success(alertMessage);

                            $scope.disableAction = false;
                            showSearchResults();
                            return;
                        }, function (response) {
                            if (response.status > 0) {
                                $scope.errorMsg = response.status + ': ' + response.data;
                            }
                        }, function (evt) {
                            $scope.progress =
                                Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
                        });
                        
                    }

and the API is very similar to what I had originally in the Upload method. I only tested with Chrome so far, but I hope that files multiple works for other browsers as well.

>Multipart form data can contain a mix of files and (for example) json objects. But I haven't used the MVC FileUpoader and don't know whether you can add additional parts on the client side before posting.

>In any case I don't see how you can create a valid FileUploadResult in javascript since it contains a HttpPostedFile instance and one of it's properties is a .NET stream.......
