Window phone Application run time error

I've Started developing Windows Phone application. Creating a new project causes the exception below to appear. I don't know what the problem might be. Can anyone help?

Solution

  • i've also had such a situation, so i just installed MS Visual Studio service pack 1 and Windows Phone SDK 7.1.1 Update and now it works:) i've seen another solution here, it didn't help me, however it may help someone else.
