How to programmatically click a CheckBox in WPF?

SO i have CheckBox and since there's no CheckBox.PerformClick() method in WPF, is there a way to click a WPF CheckBox programmatically?

I found this solution but this for Button only:

ButtonAutomationPeer peer = new ButtonAutomationPeer(someButton);
IInvokeProvider invokeProv = peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider;
invokeProv.Invoke();
