What is a good way to extend .Net Membership to track user logins

Question

As far as I can tell, the basic implementation of .Net membership records lastuserlogin but does not track each login, something I need to do now. I\'ve done some research

Answer 1

We simply created a class that extends the SqlMembershipProvider, overriding the ValidateUser method to perform whatever extra logic we want. (You just need to change the <membership> section of your web.config file to use this new membership provider).

Edit

There's really not much to it. You create a table in your schema that refers to the Guid-based user ID in the standard membership tables. You create a class to manage interaction with this table. You create your membership provider:

public class MyMembershipProvider : SqlMembershipProvider
{
    public override bool ValidateUser(string username, string password)
    {
        bool validated = base.ValidateUser(username, password);
        if (validated) 
        {
            MembershipUser user = GetUser(username, false); // built in to SqlMembershipProvider
            new LoginTracker().RegisterLogin((Guid)user.ProviderUserKey);
        }
        return validated;
    }
}

Then you register this provider in web.config:

<membership defaultProvider="MyMembershipProvider" userIsOnlineTimeWindow="60">
  <providers>
    <clear/>
    <add name="MyMembershipProvider" ... type="MyAssembly.MyNamespace.MyMembershipProvider, MyAssembly"/>        
  </providers>
</membership>

Simple!

You will need to implement a custom memberhsip provider. Take a look at this: http://msdn.microsoft.com/en-us/library/f1kyba5e.aspx
