For MVVMCross:

protected override void OnSaveInstanceState(Bundle outState)
{
    base.OnSaveInstanceState(outState);

    ScrollView sv = FindViewById(Resource.Id.dispatchScrollView);
    int posY = sv.ScrollY;

    outState.PutInt("scrollY", posY);
}

protected override void OnRestoreInstanceState(Bundle savedInstanceState)
{
    base.OnRestoreInstanceState(savedInstanceState);

    ScrollView sv = FindViewById(Resource.Id.dispatchScrollView);
    int posY = savedInstanceState.GetInt("scrollY");

    sv.Post(new Runnable(new Action(() => sv.ScrollTo(0, posY))));
}
