I closed visual studio i reopned same project again last two projects not loadded properly. Can you please give me any suggestions why i am getting issue.

Answer 1

I think you developed the application in old version of silverlight. And you laptop/computer has now the latest version.

OR

You have corrupted silverlight runtime. So remove the current installation and re-install silverlight runtime again.
