When I am trying to create a new directory in my WPF application i am getting the following error. " 'The invocation of the constructor on type 'NetworkApplication.Login' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'."

this is my line of code " DirectoryInfo di = Directory.CreateDirectory(@"C:\Windows\Newfolder1");"

thanks in advance swati

You don't have permissions to write to the windows directory, and it's bad form anyway.

I want to save licence information of my application in c:\windows along with registry. Is there any way to do this.
thanks

You should save licence information in the ApplicationData folder. Check this out for how to find it.
