動かそうとしたサンプルコードはこれ。
`var credentials = new CertificateCloudCredentials` でExceptionが発生します。

    {
        static void Main(string[] args)
        {
            var subscriptionId = "xxxxx";
            var base64Certificate = "xxxx";

            var credentials = new CertificateCloudCredentials(subscriptionId, new X509Certificate2(Convert.FromBase64String(base64Certificate)));
            using (var client = new WebSiteManagementClient(credentials))
            {
                var spaces = client.WebSpaces.List();
                foreach (var space in spaces)
                {
                    Console.WriteLine("Space: {0}", space.Name);

                    var sites = client.WebSpaces.ListWebSites(space.Name, new WebSiteListParameters { PropertiesToInclude = { "Name" } });
                    foreach (var site in sites)
                    {
                        Console.WriteLine(" " + site.Name);
                    }
                }
            }

        }
    }
}

solution?

> Turns out there's a setting in the IIS Application Pool configuration (Application Pools > Advanced Settings) to load the user profile for the application pool identity user. When set to false, the key containers aren't accessible.

とあるので、アプリケーションプールの設定を変える必要があるのでWebSiteじゃ無理？
SiteExtensionsでなんとかなるんでしょうか？
