I have even uninstalled and reinstalled the visual studio 2010 but still the error comes.
Please Help me to overcome this thank you

I just created a project using VS 2013 Pro on Windows 8.1 and had no problems. If your problem was a bug in 2010 then it's probably fixed in either 2012 or 2013 versions of VS.

Hi,

I would suggest to please check your code first as you are getting a NullException which generally comes when you have some object set to null and you are performing some actions on the same.
Moreover, if you don't have any code written and still facing the same issue, I would suggest you to uninstall Visual Studio, clear your registry and then after rebooting your system, install Visual Studio again and if still the problem prevails, you need to update your silverlight and/or Visual Studio.
I hope that would help.
