writing user management with sessions or cookies in ASP.NET MVC 3 c#

hello im new at c# and asp.net mvc 3 also. Im trying to make an alternative user management (log in, log out etc.), I have tried session and cookie but i think i couldn't so i decided to ask here. my user informations are stored in sql serve开发者_Go百科r database's table "users" and im using EF. i can not change table design so i need to do a system that it can handle this stuation.

please give me examples ( how can i do ) i read some membership's profile thing, can i use it with this EF?

thanks

You can't use the Membership providers out of the box with EF yet. Universal providers for ASP.NET are coming. see Scott Hanselman's blog for more information
