Changes to the XNA Framework API
- Media API
- SoundEffect API
- Marketplace Offers and Trial Mode Testing
- Rich Presence
- Game Invitations
- Networking Improvements
- Application Model
- Content Pipeline
XNA Game Studio 3.0 includes a media library class, which enables you to access content, such as songs, playlists, and pictures in a device's media library. It also includes support for music visualization. The media library class works with all three target platforms--Windows, Xbox 360, and Zune.
In XNA Game Studio 3.0, the SoundEffect classes enable you to generate sound effects without using the XACT tool. The SoundEffect classes integrate with the content pipeline and support WAV, WMA, and MP3 audio formats.
Marketplace Offers and Trial Mode Testing
Games can now simulate trial mode testing and present marketplace offers to players.
Games can now control the online presence information that is displayed to other players when Xbox LIVE Community Games are played.
Multiplayer game invitations are now supported across games and in-game via the Guide.
Behavior of Local Sessions
XNA Game Studio 3.0 introduces a change in the behavior of network sessions when local profiles sign out in the middle of a session. In previous versions of XNA Game Studio, a session would end whenever a player signed out. Now, profiles that sign out are removed from the session, and the session will be ended only if there are no suitable players left in the session.
- NetworkGamer.Id Property
- Gets a unique identifier that can be used to refer to this gamer in network packets.
The new enumeration SendDataOptions Enumeration.Chat enables you to mark a packet that contains chat data, such as a player-to-player message string entered using the keyboard.

- Renamed TextureCube Class constructor parameter from edgeLength to size
Renamed a number of operator == and operator != parameters that were inconsistent between platforms

This affects the following types: GraphicsDeviceCapabilities.VertexShaderCaps Structure, GraphicsDeviceCapabilities.DeviceCaps Structure, DisplayModeCollection Structure, GraphicsAdapter Class, PresentationParameters Class.
Added four new Color Structure constructor overloads: Color(float r, float g, float b); Color(float r, floag g, float b, float a); Color(Color rgb, byte a); and Color(Color rgb, float a).
Now you can set the Color.R, G, B, and A properties.
