learning class hierarchies and dependencies

hi,
is there anywhere those metadatas from system classes ('headers') in files, or any way to export those myself?
as a wpf beginner i find it quite a hard to find class hierarchy and dependencies easily, i'd prefer "find in files" method.

for example i have an instance of DoubleAnimationUsingKeyFrames and need to add keyframes, now i need to find classes inherited from DoubleKeyFrame class.
only inherited class i know of is SplineDoubleKeyFrame, but is there any others too?
it isn't that easy to search all classes from System.Windows.Media.Animation manually, and having to do it in all these similar situations.
my good old grep could do it "grep -r class.*DoubleKeyFrames" in couple of seconds.
same way i could find all classes which might also work with any other classes and functions.

if you know some other way around i have missed, i'd be more than pleased to hear of it.

[edit]

ok, i finally got that documentation app working and found somewhat decent information of inheritances.
now my only problem is to find which classes do some work together

I cannot test it on real code (I have no animated controls)

but in runtime common solution may be like this:

 foreach (var eachControl in this.Controls)
            {
                if (eachControl is IAnimatable)
                {
                    ((IAnimatable)eachControl).BeginAnimation();
                }
            }

In my example i wanted to know where i can pass DoubleAnimation.
many (all?) classes derived from System.Windows.Controls.Control accept it in BeginAnimation function (via IAnimatable interface)
It seems i can also animate some other things too, but how can i find which ones?

and no, i'm not talking about this particular class only, but all the other ones too that might come across

The question is not clear.
Do you want to know common base class (first common in hierarchie)?
