R – Alternatives to .Net Membership

asp.netasp.net-membership

Are there any alternatives\mods to .net Membership?

I find it quite restrictive;

Cant change Username, easily. You have to create a new user and copy the fields, but then you lose the primary key OR you have to edit the user table directly yourself.
Additional profile fields are stored together as one blob.

ASP.Net membership uses a provider model. That means you are completely free to implement your own membership provider, or even inherit from and extend an existing provider, as long as you follow the provider contract.

Plus one for asking about existing alternatives rather than trying to build something new yourself, though.

ASP.NET username change

cptScarlet's link was good, however I despise using stored procedures if I don't have to and I favor Entity Framework whenever possible. Here's what I did to change the user name, using EF 4.0 and .NET 4.0:

Right click project -> Add New Item -> ADO.NET Entity Data Model
Give it a proper name, I chose "MembershipModel.edmx" and click Add
Select Generate from database and click Next
Add the connection to your 'aspnetdb' database (the ASP.NET membership database)
Give it a proper name, I chose "MembershipEntities"
Click Next
Drill into Tables and select aspnet_Users
Change the Model Namespace to MembershipModel
Click Finish

Now you can add code to create the EF object context and modify the database:

public void ChangeUserName(string currentUserName, string newUserName)
{
    using (var context = new MembershipEntities())
    {
        // Get the membership record from the database
        var currentUserNameLowered = currentUserName.ToLower();
        var membershipUser = context.aspnet_Users
            .Where(u => u.LoweredUserName == currentUserNameLowered)
            .FirstOrDefault();

        if (membershipUser != null)
        {
            // Ensure that the new user name is not already being used
            string newUserNameLowered = newUserName.ToLower();
            if (!context.aspnet_Users.Any(u => u.LoweredUserName == newUserNameLowered))
            {
                membershipUser.UserName = newUserName;
                membershipUser.LoweredUserName = newUserNameLowered;
                context.SaveChanges();
            }
        }
    }
}

Note: I did not account for application ID's in my code. I typically only ever have one application using the ASP.NET membership database, so if you have multiple apps, you'll need to account for that.

R – ASP.NET Membership not populating new users

Is the Profile section in web.config using the same connectionStringName value as the Membership section? This is the first thing I would check.

Edit: Can you post your full profile config block? You should have something that defines the properties like

<profile enabled="true">

    <properties>

        <add name="UserId" type="Int32"/>

        <add name="Gender" type="string"/>

        <add name="Age" type="Int32"/>

    </properties>

</profile>
