title: Action<object, EventArgs> could not be cast to EventHandler?
body: <p>I was wiring up an event to use a lambda which needed to remove itself after triggering. I couldn't do it by inlining the lambda to the += event (no accessable variable to use to remove the event) so i set up an <code>Action&lt;object, EventArgs&gt;</code> variable and moved the lambda there. The main error was that it could not convert an <code>Action&lt;object, EventArgs&gt;</code> to an EventHandler. I thought lambda expressions were implicitly convertable to event handlers, why doesn't this work?</p>
