How to deal with CSRF?

Hi there,
How to deal with cross-site request forgery in asp.net? I'm looking for articles and plugins to use to make my website more secure. If you have suggestions, articles, reviews, please drop them in this thread.

3) Can I also prevent data loading from other sites, such as images host on my server embeded on external websites?
Thanks!
