I just realized I can add an event handler in two ways:

Consider an event handler like so:

private void MyEventHandler()
{}

Method 1: Instantiate a new delegate

MyObject.MyEvent += new Action(MyEventHandler);

Method 2: Add event handler without instantiating a new delegate

MyObject.MyEvent += MyEventHandler;

Is there any difference in between these two implementations that should be considered?

There is no difference, the generated IL is the same. The shorter form was introduced in .net/c# 2.0 as a convenience function, although Visual Studio still does the first form on Tab Completion.

See this question for some more info.
