Converting ControlTemplate XAML to C#

Question

I have been stumped with trying to convert the following code into pure c#. This XAML code is from Cavanaghs blog on how to make rounded corners on anything. The code work

You do not want to know this. Seriously, you don't, it's a nightmare.

Edit: If i did not make any mistake this is the translation of your code...

Setter setter = new Setter();
setter.Property = ListViewItem.TemplateProperty;
ControlTemplate template = new ControlTemplate(typeof(ListViewItem));
var grid = new FrameworkElementFactory(typeof(Grid));
var border = new FrameworkElementFactory(typeof(Border));
border.SetValue(Border.BackgroundProperty, Brushes.White);
border.SetValue(Border.NameProperty, "mask");
border.SetValue(Border.CornerRadiusProperty, new CornerRadius(15));
grid.AppendChild(border);
var stackPanel = new FrameworkElementFactory(typeof(StackPanel));
stackPanel.SetValue(StackPanel.BackgroundProperty, Brushes.Beige);
var visualBrush = new FrameworkElementFactory(typeof(VisualBrush));
visualBrush.SetBinding(VisualBrush.VisualProperty, new Binding() { ElementName = "mask" });
stackPanel.SetValue(StackPanel.OpacityMaskProperty, visualBrush);
var gridViewRowPresenter = new FrameworkElementFactory(typeof(GridViewRowPresenter));
gridViewRowPresenter.SetValue(GridViewRowPresenter.ContentProperty, new TemplateBindingExtension(GridViewRowPresenter.ContentProperty));
gridViewRowPresenter.SetValue(GridViewRowPresenter.ColumnsProperty, new TemplateBindingExtension(GridView.ColumnCollectionProperty));
stackPanel.AppendChild(gridViewRowPresenter);
var textBlock = new FrameworkElementFactory(typeof(TextBlock));
textBlock.SetValue(TextBlock.BackgroundProperty, Brushes.LightBlue);
textBlock.SetBinding(TextBlock.TextProperty, new Binding("News"));
stackPanel.AppendChild(textBlock);
grid.AppendChild(stackPanel);
template.VisualTree = grid;
setter.Value = template;

Edit: There is still a bug left, the VisualBrush cannot be created like that, the rest seems to work.
