The most hyped new feature in Visual Studio 2008 is LINQ, which stands for Language INtegrated Queries. It's awesome, and you'll be using it to talk to SQL, Objects and everything in between. Specifically to LINQ to Objects, this mechanism has the ability to query anything that implements IEnumerable<T>, which is a nice feature because it allows for creating complex logic to search collections by.
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs,
live-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
