Load dll dynamically

Question

Hai all,

My Problem is, i want to create instance for one xaml from assembly without adding reference.

var folder = Package.Current.InstalledLocation;
            folder = await folder.GetFolderAsync("Notes");
            foreach (var file in await folder.GetFilesAsync())
            {
                if (file.FileType == ".dll" && file.DisplayName == "Popup")
                {
                    file.CopyAsync(Package.Current.InstalledLocation);
                    var assemblyName = new AssemblyName(file.DisplayName);
                    var assembly = Assembly.Load(assemblyName);
                    Type myType = assembly.GetType("Popup.TestPage");
                    object obj = Activator.CreateInstance(myType);
                    this.Content = obj as FrameworkElement;
                }
            }

i have wrote above code.. it will work if i add reference. It will not work without reference.

Any suggestions.. Please help techies..
