    copied!<p>I am getting a <code>CommunicationException</code> when trying to do a callback to a client, I know that the problem lies within this class, although I can't figure out what member is having trouble being serialized.</p> <pre><code>[DataContract] public sealed class DirectoryInformation : FileSystemInfo { public override void Delete() { Directory.Delete(FullName); } [DataMember] public override string Name { get { return Path.GetFileName(FullName); } } [DataMember] public override bool Exists { get { return Directory.Exists(FullName); } } [DataMember] public int Size { get; private set; } #region Ctor public DirectoryInformation(string directory) { FullPath = directory; Refresh(); CalculateDirectorySize(directory); } public DirectoryInformation() { } #endregion #region Private Methods private void CalculateDirectorySize(string directory) { if (!IsDirectoryAccessible(directory)) return; Size = Size + (int) Directory.GetFiles(directory).Select(x =&gt; new FileInfo(x)).Sum(x =&gt; x.Length); foreach (var dir in Directory.GetDirectories(directory)) CalculateDirectorySize(dir); } private static bool IsDirectoryAccessible(string directory) { try { Directory.GetFiles(directory); return true; } catch (UnauthorizedAccessException) { return false; } } #endregion } </code></pre> <p>I have already checked and it is not one of the members of <code>FileSystemInfo</code>, since the problem persisted even when removing the inheritance. I already made sure I am assigning all the members with <code>DataMember</code> attribute and there is a standard contructor.</p> <p>I think what is causing the problem is something I am not aware of the existence, but what could it be?</p>
