UPDATE: I’ve changed the wording to reflect Rob’s post, which specifically mentions launch…so until I can confirm what the actual release date is, I’m sticking with his wording to be clear. Thanks to reader Doug Holland for asking me to clarify.

Per Rob Caron, the new release launch date for Visual Studio 2010 and the .NET Framework 4 is:

April 12th, 2010!

Also, I’ve updated my Silverlight Countdown widget to reflect the new date…if you’re hosting the widget, please update the TargetDate initParam to “04/12/10”. Updated <object> tag markup below:

   1: <div id="silverlightControlHost">
   2:     <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="190" height="180">
   3:        <param name="initparams" value="TargetDate=04/12/10" />
   4:        <param name="source" value="http://gdtest.members.winisp.net/ClientBin/SilverCountDown.xap"/>
   5:        <param name="onError" value="onSilverlightError" />
   6:        <param name="background" value="black" />
   7:        <param name="minRuntimeVersion" value="3.0.40624.0" />
   8:        <param name="autoUpgrade" value="true" />
   9:        <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none">
  10:           <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/>
  11:       </a>
  12:   </object>
  13:   <iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe>
  14: </div>
