Recently I have installed Visual Studio 2010 RC in accordance with Silverlight 4 toolkit, these things are working fine but the problem is that the designer is not working at all. Previously when I was working with WPF, the designer was working without any problem. As far as know this problem is started after I have installed Visual Studio 2010. I am getting exception for System.Runtime.InteropServices.COMException. It is possible that the reason for this problem may be different but I want to know why Designer doesn't work with Silverlight 4 RC, because I want to work with both of them.
