Garbage Collection when Attached dependencyobject is destroyed \ disconnected

it should still fix some issue As I understand the new property system in the WPF, the DependecyObject itself stores the value. In your example, this would be the textblock. Don't get confused as you call a static member - it is supposed to be implemented like: code :
element.SetValue(DockPanel.TopProperty, value);

Reading Attached Property from Non-DependencyObject
By : user3230166

To fix this issue You read it backwards: you can't apply an attached property to a non-DependencyObject. You can however define an attached property on a class not deriving from DependencyObject. Typically a static class, like FocusManager in WPF. x:Name is not an attached property: it's a directive. In the common case of a FrameworkElement, it's the same as FrameworkElement.Name. In the case of a custom class, its purpose is to define a field of the same name (which should be your case: you now have Refresh and Print fields available from code-behind). In every case (except inside a ResourceDictionary), it's added to the current XAML namescope. code :
var dictionary = (INameScopeDictionary) NameScope.GetNameScope(yourWindow);

List properties of a DependencyObject?
By : user3580468

I hope this helps you . You can do this using reflection, since DependencyProperties are (usually?) stored in public static fields of type DependencyProperty: code :
private static IEnumerable<DependencyProperty> GetDependencyProperties(DependencyObject o)
{
return from field in o.GetType().GetFields(BindingFlags.Public |
BindingFlags.FlattenHierarchy |
BindingFlags.Static)
where field.FieldType == typeof(DependencyProperty)
select (DependencyProperty)field.GetValue(null);
}

Localizing attached properties in XAML/WinRT
By : Juan Liner

To fix the issue you can do You need to handle attached properties a bit differently, i.e. their namespace must be included in the reource key like this: code :
FoldersPageAppBarAddFolderButton.[using:Windows.UI.Xaml.Automation]AutomationProperties.Name

WinRT / UWP: Loading RelativePanel with XamlReader causes XamlParseException with RelativePanels Attached Properties
By : 최태훈

hop of those help? I'm trying to use the XamlReader to parse a XAML File on during runtime. Unfortunately I get a XamlParseException when the XamlReader tries to read the Relative Attributes like RelativePanel.Below. , Replace the element name in code :
RelativePanel.AlignRightWith="logoBorder"
RelativePanel.AlignRightWith="{Binding ElementName=logoBorder}"
