migration

Hi,

I moved my app from silverlight 3 VS2010 to a system having Silverlight 4 and VS 2010. When I open the Solution I get the following error in the MainPAge.xml. What is wrong.

Could not resolve mscorlib for target framework 'Silverlight,Version=v3.0'. This can happen if the target framework is not installed or if the framework moniker is incorrectly formatted.
