Silverlight 3 Beta for developers was unveiled at MIX09 last week. We created a separate build of Telerik RadControls for Silverlight3. Download the bits here (it is available in your client.net account under Downloads > RadControls for Silverlight > Latest Internal Builds).
There are no new features to the controls, only that they are compiled against the Silverlight 3 runtime. You can download the controls now and enjoy the latest features added to the Microsoft Silverlight3 platform.
Please note that Silverlight3 is a developer beta release only! This means there is no “go-live” licensing available and the end-user runtime of Silverlight 3 is not available.
If you have any feedback on what you would like Telerik to create for the Silverlight3 platform - please let us know. Our main focus for the Q2 release will be mainly on the Silverlight2 platform. We will be adding the Silverlight3 features once the Silvrelight3 runtime has a “go-live” license.
