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 Silverlight 4 Developer Runtime v4.0.50524.0.

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

  1. You develop SL 4 on VS2008? VS 2008 don't support preview xaml

  2. You need to upgrade to VS2010 to use SL 4 better.

  3. Is what is likely happening is that you have the standard version of the Silverlight runtime and you need to install the developer runtime for Silverlight. Blend will install and run with the standard verison of the silverlight runtime, but Visual Studio requires the developer version of the runtime. This issue is fixed in the RTM version of Visual Studio.

    For now, if you hit this issue, please install the silverlight developer runtime from this link: http://go.microsoft.com/fwlink/?LinkId=146060

  4. Here is a similar case, maybe it will give you some helps:

If above doesn't give you helps, it's better that you can zip up your code for us so that we can test it.
