I need your help!
I have some usercontrol in which hovering mouse on this keyword threw an strange error
class Puzzle : UserControl {
public void Animate()
{
this.SetValue(Canvas.TopProperty, 0.0); // expression has been evaluated and has no value
}
}
what is wrong with this approach?

From your followup comment, you are trying to watch a method call on a method that has a void return type.
The debugger is trying to be helpful by telling you it has no value.
Try adding a watch on the matching GetValue method instead :)
