What are some of the must know concepts in ASP.NET?

I am giving a small presentation to a group of Java developers and looking for some core areas to target. Ideally I would like to only talk about the core concepts in ASP.NET.

I am coming up with

• Authentication
• Sessi开发者_开发百科on State
• ASP.NET MVC
• LINQ (more .net)

Any more that I should be considering?

One of the most important things to learn is the ASP.net lifecycle. It makes debugging much more worthwhile...

For ASP.net WebForms -

MSDN Documentation

Useful cheat sheet

It is important to keep the life cycle in mind when developing web based applications.

I'd focus on ASP.NET MVC (because while MVC is bread and butter in Java, that's a pretty cool implementation) and LINQ, especially the runtime query construction you can do with something like PredicateBuilder (because Java can't do that and it's a very good way to demonstrate the unique capabilities of C#).
