Microsoft has released the latest version of its game development suite targeted to Xbox 360, Windows PC and Zune. C# 3.0 is now supported as well as several key functionalities that were badly needed by hobbyist developers such as “Trial mode” releases, “in-game invites” using the Xbox LIVE multi-player platform, and “1-click installation” of Windows games with automatic asset compression of content to improve download times.

Microsoft has finally announced that premium members of the XNA Creators Club will be able to sell the games they have developed through the Xbox Live Marketplace.

As long as you have completed your Xbox 360 game, you send it to the Creators Club community to be peer reviewed and if successful could earn as much as 70% of the 200-800 Microsoft points selling price range (paid quarterly, in actual cash).
