Replace Guid serialization

[rushfrisby]

To work around protobuf-net's handling of Guids which other languages don't know about I've ended up doing this a lot:

[DataContract]
public class TestResult
{
    public Guid Id { get; set; }

    [DataMember(Order = 1)]
    private string IdValue
    {
        get
        {
            return Id.ToString();
        }
        set
        {
            Id = Guid.Parse(value);
        }
    }
}

This can get messy if Guids are used a lot so I'd like to use a surrogate instead:

RuntimeTypeModel.Default.Add(typeof(Guid), true).SetSurrogate(typeof(GuidSurrogate));

however, I get this runtime exception:

System.ArgumentException: 'Data of this type has inbuilt behaviour, and cannot be added to a model in this way: System.Guid'

Is there any way to get around this?

Not currently, no.

Not sure if this will help (for others also as I realise this post comes a little late) but there are some ideas here floating around here:

• Provide support for UUID type (a.k.a. GUID) protocolbuffers/protobuf#2224
