Question

How could I serialize/deserialize VesionSet?

var serializer = new XmlSerializer(typeof(VersionSet));

causes InvalidOperationException: To be XML serializable, types which inherit from IEnumerable must have an implementation of Add(System.Object) at all levels of their inheritance hierarchy. Xtensive.Storage.VersionSet does not implement Add(System.Object).

var stream = new MemoryStream();
var serializer = new XmlSerializer(typeof(VersionInfo));
serializer.Serialize(stream, versions.First().Value);

Using this - there are no data of tuple.

Serialization/Deserialization requied for transfer to/from webclient.

XmlSerializer capabilities aren't sufficient here. Use NetDataContractSerializer (definitely must work) or DataContractSerializer to do this.
You must have current Session available on deserialization.

P.S. Right now Denis works on N-tier sample for DO4. So we'll show how to transfer the state and apply the operations to Domains today or tomorrow. There are really many non-obvious things you must care about. But in the end everything works.

So do i waiting for example. But for now i use Json.NET serialization to string, string to byte[] and compress this byte array with MiniLZO with goood compression rate, maybe better than xml serialization. I select serializing with Json.NET because of silverlight, where NetDataContractSerializer is not supported.
