boiler settlement formula deputy - there anything bad code?

i've recently combined twin (unrelated) methods reinstate lots boiler-plate formula winforms application. distant i tell, work ok, nonetheless i need reassurance/advice presumably there problems i competence missing.

(from memory)

static category safeinvoker
{
    //utility prevaricate boiler-plate invokerequired code
    //usage: safeinvoker.invoke(myctrl, () => myctrl.enabled = false);
    open stationary vacant invoke(control ctrl, movement cmd)
    {
        (ctrl.invokerequired)
            ctrl.begininvoke(new methodinvoker(cmd));
        else
            cmd();
    }

    //replaces onmyeventraised boiler-plate code
    //usage: safeinvoker.raiseevent(this, myeventraised)
    open stationary vacant raiseevent(object sender, eventhandler evnt)
    {
        var handler = evnt;
        (handler != null)
            handler(sender, eventargs.empty);
    }
}

edit: associated doubt

update

following deadlock problems (related ), i have switched plead begininvoke (see an reason ).

another update

regarding second snippet, i am increasingly prone 'empty delegate' pattern, fixes problem 'at source' dogmatic eventuality directly an lifeless handler, so:

event eventhandler myeventraised = nominee {};
