Apple announced the dates for its 2012 Worldwide Developers Conference and kicked off ticket sales Wednesday morning, and sold out within two hours. The event runs from June 11 through June 15, and if you don’t already have tickets, you won’t be getting in the door.

Tickets were priced at US$1,599 for the event, and were limited to one per person or up to five per organization. Even with those limitations, and the fact that developers in some parts of the world are probably still asleep and don’t even know the event was announced, Apple managed to run through all of its tickets in short order.

Apple uses the annual event to give iOS and OS X developers details on the company’s roadmap, and also offers developers the opportunity to work directly with Apple engineers for a few days.

The event will include over 100 technical sessions presented by Apple engineers, 100 hands-on labs where developers can get help with their own code from Apple, and will also include Apple’s traditional Design Awards for Mac, iPhone and iPad apps.

For developers that are missing out on the conference, Apple will be posting videos of the sessions on its website. That’s not the same as getting to be there in person, but at least the content will be available for registered developers that didn’t get tickets in time.
