IXamlDirect relativePanel = xd.CreateInstance(XamlTypeIndex.RelativePanel);

IXamlDirect childrenCollection = xd.GetXamlDirectObjectProperty(relativePanel, XamlPropertyIndex.Panel_Children);

IXamlDirect button = xd.CreateInstance(XamlTypeIndex.Button);
xd.InsertIntoCollectionAt(childrenCollection, 0, button);

XamlDirect^ xd = XamlDirect::GetDefault();
