Using the Azure API, how do I list and add virtual directories to a website?

I am trying to add a Virtual Directory to an Azure Web Site from a WinForms Application using the Azure API. I can enumerate the WebSites on in my webspace, but I cannot find a method that allows me access to the Virtual Directories in the WebSite.

Here is my code:

        string certPath = Properties.Settings.Default.AzureCertificatePath;
        string certPassword = Properties.Settings.Default.AzureCertificatePassword;
        string subscriptionId = Properties.Settings.Default.AzureSubscriptionId;
        var cert = new X509Certificate2(certPath, certPassword, X509KeyStorageFlags.MachineKeySet);

        var cred = new CertificateCloudCredentials(subscriptionId, cert);

        using (var client = new WebSiteManagementClient(cred))
        {
            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" } }); ***// Where do I find out what properties can be included in this array?***
                foreach (var site in sites)
                {
                    ***// What goes here to show the virtual directories in this specific website??????***
                }
            }
        }
