**for creating a CustomerMemberShipClass** your class must implement System.Web.Security.MembershipProvider abstarct class. and you override the method ValidateUser()
in this ValidateUser() you have to write your own logic based on which you want authenticate user and return true or false according to it.

Sample ValidateUser method 
  public override bool ValidateUser(string username, string password)
        {
           int count=db.GetAll().Where(x => x.UserEmail == username && x.password == password).Count();
           if (count != 0)
               return true;
           else
               return false;
        }

later in web.config file you have add the fallowing under  element



      
        
        
      
    

after doing this you can validate user using **MemberShip.Validate(Username,password)** which returns true or false based on ur code in ValidateUser() in CustomMemberShipProvider class and this will also set **[Authorize] attribute**

**for creating a CustomRoleProviderClass** your class must inherit System.Web.Secuirty.RoleProvider and override the appropriate method to get the roles for the user

SAmple method for getting roles for user


 public override string[] GetRolesForUser(string username)
        {
            string[] str={db.GetAll().Where(x=>x.UserEmail==username).FirstOrDefault().Role};
            return str;
        }

after this you must add the fallowing in web.config file in  element


      
        
        
      
    

 and after this u can check the role of the user using attribute **[Authorize(role="admin"])** and in Razor view you can check using User.IsinROle("A").
