Why is there no edit in Blend option in WPF4? <p>I am a Silverlight 4 developer getting started with WPF4. In Silverlight 4, there is option available in menu "Edit in Blend" when you right click on any xaml file. Why is this option not available in WPF4?</p> <p>Do I need to download some patch for Visual Studio 2010?</p> <p>Thanks in advance :)</p>
