I'm please to announce the general availability of the Silverlight 5 release candidate (RC) as of approximately 10am Pacific this morning (give the servers a few minutes to replicate the links and content). Hop on over to the downloads page on Silverlight.net and grab the bits and start using them.

　　This RC is a developer-only release (there is no go-live license)， designed to get you read for the final release later this year. Use this release to update your SL5 beta code to work with the namespace and reference changes, and to use the new features.

　　This isn't the final release, so please go out and test it, and report any bugs you find.

　　In addition to what we had in the beta, some of the more exciting features included in this release are:

• P/Invoke support for calling native functions
• 64 bit support (yay!)
• Vector (Postscript) Printing
• Remote Control and Media Command Support
• DataContextChanged event
• In-Browser Trusted Applications
• PivotViewer Control
• Power awareness for media apps (keep the PC alive while a movie is playing, for example)

　　In addition,we made several changes to the locations of some of the XNA namespaces and files. For example,you'll find that much of the 3d stuff has moved to a different DLL. We've also changed the Linked Text feature to use the read-only RichTextBlock rather than the editable RichTextBox. I've updated both posts and their downloadable source code to reflect the changes.

　　Please go ahead and refer back to the Silverlight 5 beta information for other features. Here are some of my beta posts, updated for the RC:
