XElement.ToString returns encoded text
I am sure people who do XML on a day to day basis would not find surprising but I think it was pretty cool to see that when I call ToString on my XML, I get back my entire XML with whitespace preserved and also all text is encoded for me automatically. I created my XML using .net 2.0 api and saw the same behavior so I guess this was not a new feature but definitely a good default option to encode your text before outputting it to the user. Here is simple example that illustrates this behavior.
As you can see from the above code, my title and author value have some html tags that gets encoded when i output the content to the console.
