       {
           IsolatedStorageFile isfData = IsolatedStorageFile.GetUserStoreForApplication();
           XDocument doc = null;
           IsolatedStorageFileStream isfStream = null;
           if (isfData.FileExists(strXMLFile))
           {
               isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.Open, isfData);
               doc = XDocument.Load(isfStream);
               isfStream.Close();
           }
           else
           {
               doc = XDocument.Load(strXMLFile);
               isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.CreateNew, isfData);
               doc.Save(isfStream);
               isfStream.Close();
           }

           var vData = from s in doc.Descendants("Row") select new ColData(s);
       }


       public void Write(string strXMLFile)
       {
           XElement xml = new XElement("Tabel",
                           from p in this
                           select p.Information);

           IsolatedStorageFileStream isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.Open, IsolatedStorageFile.GetUserStoreForApplication());
           xml.Save(isfStream);
           isfStream.Close();

       }

check with below methods, if you have setup development environment in windows 8 PC, you better debug line by line and check what is going wrong.
To write a file:

C#

public async Task WriteFile(string fileName, string text)
{
    IStorageFolder applicationFolder = ApplicationData.Current.LocalFolder;

    IStorageFile storageFile = await applicationFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);

    using (Stream stream = await storageFile.OpenStreamForWriteAsync())
    {
        byte[] content = Encoding.UTF8.GetBytes(text);
        await stream.WriteAsync(content, 0, content.Length);
    }
}

To read a file:

C#

public async Task<string> ReadFile(string fileName)
{
    string text;
    IStorageFolder applicationFolder = ApplicationData.Current.LocalFolder;

    IStorageFile storageFile = await applicationFolder.GetFileAsync(fileName);

    IRandomAccessStream accessStream = await storageFile.OpenReadAsync();

    using (Stream stream = accessStream.AsStreamForRead((int)accessStream.Size))
    {
        byte[] content = new byte[stream.Length];
        await stream.ReadAsync(content, 0, (int) stream.Length);

        text = Encoding.UTF8.GetString(content, 0, content.Length);
    }

    return text;
}</string>
