Where to find XAML namespace d=“http://schemas.microsoft.com/expression/blend/2008” mapping library?-Collection of common programming errors

In every default WPF window as below, there are four namespaces are referenced. I know xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” and xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” are mapping library PresentationCore.dll and PresentationFramework.dll. But where can I find the library files mapping namespace xmlns:d=”http://schemas.microsoft.com/expression/blend/2008″ and xmlns:mc=”http://schemas.openxmlformats.org/markup-compatibility/2006″?
