Today, during the Day 2 Keynote of the DevConnections event in Las Vegas, Microsoft announced that Silverlight 4’s final release will be on April 15th this week and available to download.

I think many people were hoping for a release today, but oh well…

Today’s live streamed keynote included demonstrations of Silverlight 4’s features and associated productivity enhancements in Visual Studio 2010.

Note that there will also be an ‘RC’ Tools release for Visual Studio and an Expression Blend 4 Preview update.
