After installing the Membership Default Provider in VS2012 by Library ... I cant see any of the control when I drag and drop it. It give the error of :

Error Creating Control" - Object reference not set to an instance of an object.

What I do ... should I reinstall it ? I have tired all the solutions given over internet but failed.

That's weird. Did you try uninstalling the providers again? Also, is your web.config file valid? Try replacing it with mine for that chapter.

Cheers,

Imar
