In C# Is there a fundamental difference between using
event EventHandler<myeventargs> and
EventHandler<myeventargs>
As they both produce the same effect from what I can see apart from using the event keyword gives you a different icon in intellisense.

They seems to be alike, but really different.
With event keyword, you are making them something like properties, which means you can register them in public, while maintain a private back-end.
However, without event keyword, it's just a public delegate field, and anyone can remove or modify others' events, which is a "encapsulation disaster" as @Jonskeet said.
Check this article by Jon Skeet, it's very helpful :)
Edit:
What I summarized above was not my original thinking, all credits to @Jonskeet's post.
