Silverlight 4 Developer Release
The Developer Release of Silverlight 4 is now available and works with Visual Studio 2010.
Silverlight 4 delivers a full suite of powerful capabilities to business application developers, bringing the best-of-breed .NET platform to browser-based experiences. Silverlight provides an ideal platform for developing and deploying modern business applications for both customer facing and staff-facing applications.
Note this is a developer release only for testing, which means there is no “go-live” license and no end-user runtime.
For Silverlight 4 development, you will need the latest version of Visual Studio 2010, which can be installed side-by-side with Visual Studio 2008 SP1. Note there is a problem installing Visual Studio 2010 if you already have the Silverlight 3 SDK installed.
