This package contains web helpers to easily add functionality to your site such as Captcha validation, Twitter profile and search boxes, Gravatars, Video, Bing search, site analytics or themes.
This package is not compatible with ASP.NET MVC.
See the version list below for details.
If the package is installed in an ASP.NET MVC 3 site, the site will not work. If you’ve already installed the package into an MVC 3 application, uninstall it. (If the MVC 3 site does not work even after you have uninstalled the package, you might need to reinstall the ASP.NET MVC 3 packages as well.)
If your application is ASP.NET MVC 4 you should install Microsoft.AspNet.Web.Helpers.Mvc instead.
