Vista - Loading User control at runtime

Hello All,
Is it possible to load WPF UserControl in my WPF app using
System.Reflection. I don't want to add reference to the UserControl
assemblies at the compile time.

Though I tried ...

---------------------------------------------
Assembly SampleAssembly;
Type myColorPicker;

SampleAssembly = Assembly.LoadFrom("C:\\Program Files\\Microsoft
SDKs\\Windows\\v1.0\\samples\\AllWinFXsamples\\WindowsPresentationFoundation\\Demos\\ColorPicker\\CSharp\\ColorPickerLib\\bin\\Debug\\ColorPickerLib.dll");

myColorPicker = SampleAssembly.GetTypes()[0];

object ibaseObject = Activator.CreateInstance(myColorPicker);

colorPicker = (Control)ibaseObject;


Grid.SetRow(colorPicker, 0);
Grid.SetColumn(colorPicker, 0);
myGrid.Children.Add(colorPicker);
---------------------------------------------

I am dont see the control.

Is there an alternate way to load a WPF user control without adding
references to the assemblies
Regards
