これが私がそれをした方法です（おそらく最良のアプローチではありませんが、それは機能します）：
- 標準のメンバーシップテーブルを作成します
2.ユーザーをGuidの代わりに通常のIDにリンクする別のテーブルを追加します。これにより、誰かがユーザープロファイルを表示したいときに、URLにGuidを入力する必要がなくなります。また、フィールドDisplayNameがあるため、複数のユーザーが同じDisplayNameを持つことができます。
C＃用のOpenIDライブラリを使用する
- 次のコードスニペット（これはまだ完了していませんが、機能します）をアカウントコントローラーに追加します。

認証する場合：
@using (Html.BeginForm("LoginOpenId", "Account", FormMethod.Post))
{
@Html.Hidden("returnUrl", Request.QueryString["ReturnUrl"])
<p>Login using:</p>
<input type="submit" class="login-btn facebook" name="provider" value="http://facebook-openid.appspot.com/" />
<input type="submit" class="login-btn google" name="provider" value="https://www.google.com/accounts/o8/id" />
<input type="submit" class="login-btn yahoo" name="provider" value="http://me.yahoo.com/" />
}
ご覧のとおり、これは完了していません。非公式のFB OpenIDプロバイダーを使用していますが、OAuthを使用してFbログインを個別に処理するケースを作成できます。
