To use Profiles in the manner you describe requires a Web Site project. Your question implies that you have a Web Application project.
Using profiles in a Web Application project is a little more work than with a Web Site as the dynamic ProfileCommon class is not generated for you.
Here are some references to help you understand the differences.
And here is a tool that can make using profiles in Web Applications easier.
This URL describes how to work around the issue with Profiles within a Web Application: Using ASP.Net Profile Feature in a Web Application Project
Add this namespace in your page System.Web.Profile
using System.Web.Profile;
The problem is that Profile Already exists in web.config. So you have to add your properties into the profile, erase the using System.Web.Profile and write it again (Using System.Web.Profile;).
