When vertical dimension larger than the horizontal, the zoom appears as follows.

WpfMapControl_ZoomToRegion_VerticalFitting

Note that the padding factor is divided by two for each side of the region.

In the instance of the following code

GeoPoint p1 = new GeoPoint(10, 10);
GeoPoint p2 = new GeoPoint(30, 60);
mapControl.ZoomToRegion(p1, p2, 0.3);

the result should look like the following.
