Wolf Schmidt announces that the MSDN Online documentation for Silverlight 4 is now live.
If you have been looking at the documentation for the last 6 months or so, you may be used to seeing two entries in the MSDN Table of Contents at this spot: one for Silverlight 3, one for Silverlight 4 (Beta or RC). Now, there is just a single "Silverlight" node.
Generally the information in documentation is written as it applied to Silverlight 4. In cases where there is a difference in behavior if you are still targeting Silverlight 3, the difference is often called out in a separate section of the topic. Or in some cases there are entirely separate topics for a subject area as it applies to Silverlight 3.
