Debug Error - Silverlight 3

Unable to start debugging. The Silverlight managed debugging package isn’t installed.
Recently, when I setup my SL 3.0 development environment on my new laptop, I can across a new error “ Unable to start debugging. The Silverlight managed debugging package isn’t installed.”
Unable to start debugging
“Fig: SL Error - Unable to start debugging “

If you installed latest version of Silverlight (Silverlight 4), it may break the your current Silverlight development environment. After in the Silverlight 4 installation, if you try to debug any Silverlight 3 project, you will get a message from Visual Studio 2008, saying “Unable to start debugging. The Silverlight managed debugging package isn’t installed.”
To fix this error, install the Silverlight Developer Run time. To get it Click here

I have also face the same problem and fixed now. Still I never see design view on my silverlight application

In SL 3.0 tools dont have XAML design preview why??? (SL 2.0 having that).

Hi,

I was able to see the XAML design view in SL 2.0 but in SL 3.0 I also dont get the XAML design view. May be there is some problem with the SL tools. But in VS 2010 you get the XAML design view.
