在带有实体框架的新MVC 3应用中使用ProfileProvider是一个坏主意吗？

profile.FirstName = viewModel.FirstName;

<profile enabled=\"true\" defaultProvider=\"EfProfileProvider\" inherits=\"Data.BOHProfile\" automaticSaveEnabled=\"true\">
    <providers>
        <clear />
        <add name=\"EfProfileProvider\" type=\"Data.Providers.EfProfileProvider\" connectionStringName=\"BOHEntities\" applicationName=\"BOH\" />
    </providers>
</profile>

public class BOHProfile : ProfileBase, IBOHProfile
{
    public virtual string FirstName
    {
        get { return base[\"FirstName\"] as string; }
        set { base[\"FirstName\"] = value; }
    }

    public virtual string LastName
    {
        get { return base[\"LastName\"] as string; }
        set { base[\"LastName\"] = value; }
    }

    public virtual string City
    {
        get { return base[\"City\"] as string; }
        set { base[\"City\"] = value; }
    }

    public static BOHProfile CurrentUser()
    {
        return (BOHProfile)(ProfileBase.Create(Membership.GetUser().UserName));
    }

    public static BOHProfile CurrentUser(string userName)
    {
        return (BOHProfile)(ProfileBase.Create(userName));
    }
}

    public override SettingsPropertyValueCollection GetPropertyValues(SettingsContext context, SettingsPropertyCollection collection)
    {   
        var uow = new EfUnitOfWork();
        var profileRepo = new ProfileRepository(new EfRepository<Profile>(), uow);
        var data = profileRepo.FetchProfileData(context[\"UserName\"].ToString(), ApplicationName);

        return data != null ? ProviderUtility.ConvertToSettingsPropertyValueCollection(data) : null;
    }

    public override void SetPropertyValues(SettingsContext context, SettingsPropertyValueCollection collection)
    {
        var data = ProviderUtility.ConvertFromSettingsPropertyValueCollection(collection);
        var uow = new EfUnitOfWork();
        var profileRepo = new ProfileRepository(new EfRepository<Profile>(), uow);

        profileRepo.SaveProfileData(context[\"UserName\"].ToString(), ApplicationName, data);
        profileRepo.Save();
    }
