ASP.NET custom RoleProvider error

I'm trying to use this article to learn about custom roleproviders, but I'm getting this error:

Could not load type 'TestRoles.SimpleRoleProvider'.

The relevant section from my web.config:

<roleManager enabled="true" defaultProvider="SimpleRoleProvider">
        <providers>
            <add name="SimpleRoleProvider" type="TestRoles.SimpleRoleProvider"/>
        </providers>
    </roleManager>

The RolesProvider.cs class:

public class TestRoles{
public class SimpleRoleProvider : RoleProvider
{
    public override string[] GetRolesForUser(string username)
    {
        List<string> roles = new List<string>();
        roles.Add("Guest");
        if (username.Equals("Dave"))
            roles.Add("Admin");
        return roles.ToArray();
    }
 }
 }

From this error, it seems like it can't find the RoleProvider. Any ideas?

From stackoverflow

• Well it seems to me that your namespace is wrong:

  TestRoles.SimpleRoleProvider

  Your namespace must me TestRoles and your class name SimpleRoleProvider

  Change your class TestRoles to namespace and make sure that you don't have any other namespace above TestRoles like xy.TestRoles.SimpleRoleProvider

  Ethan : Oh boy, that was it. I don't know how long I spent staring at that code without even realizing I'd typed 'class' instead of 'namespace'. Thanks!
