If anyone is wondering how I applied Ed Plunkett's answer, here is the code:

var saveDialog = new SaveFileDialog
{
    CreatePrompt = true,
    OverwritePrompt = true,
    Filter = "Project Markdown File | *.pmd"
};

var result = saveDialog.ShowDialog();

if (result != null)
{
    if (result == true)
    {
        if (!Directory.Exists(saveDialog.FileName + "_temp"))
        {
            var parentFolder = Directory.CreateDirectory(saveDialog.FileName + "_temp").FullName;

            var mp = new MarkdownParser();
            // Generate HTML
            var html = mp.Parse(document.Markdown.Markdown);

            var markdownFilePath = parentFolder + "\\" + saveDialog.SafeFileName + ".md";
            var htmlFilePath = parentFolder + "\\" + saveDialog.SafeFileName + ".html";
            var metadataFilePath = parentFolder + "\\" + saveDialog.SafeFileName + ".xml";
            // Generate MD file
            using (var sw = new StreamWriter(markdownFilePath))
            {
                sw.Write(document.Markdown.Markdown);
            }
            // Generate HTML file
            using (var sw = new StreamWriter(htmlFilePath))
            {
                sw.Write(html);
            }
            // Generate XML file
            document.Metadata.FileName = saveDialog.SafeFileName;
            var gxs = new GenericXmlSerializer();
            gxs.Serialize(document.Metadata, metadataFilePath);
            // Generate style
            var cssFilePath = AppDomain.CurrentDomain.BaseDirectory + "Styles\\github-markdown.css";
            if (!Directory.Exists(parentFolder + "\\Styles"))
            {
                Directory.CreateDirectory(parentFolder + "\\Styles");
            }

            if (!File.Exists(parentFolder + "\\Styles\\github-markdown.css"))
            {
                File.Copy(cssFilePath, parentFolder + "\\Styles\\github-markdown.css");
            }
            // Generate the package
            ZipFile.CreateFromDirectory(parentFolder, saveDialog.FileName);
            // Update the view
            var saveResult = new SaveResult
            {
                FileName = saveDialog.SafeFileName,
                Source = htmlFilePath.ToUri(),
                TempFile = saveDialog.FileName + "_temp"
            };
            return saveResult;
        }
    }
}
