Problem solved for me. Check by Control panel, Programs all the installed Silverlight programs.

If you installed Silverlight 4, then check for Microsoft Silverlight in control panel uninstall programs (Silverlight Developer runtime) by selecting the row

It would not be the version higher like 5.0.00.. (You can see on bottom status)

If so (5.0), uninstall Microsoft Silverlight (5.0 version)

Download from here

Silverlight 4 Developer Runtime v4.0.50524.0:


and install it, then open your project. it will solve your problem.
