    <p>I'm having issues deserializing a Guid when the Guid is defined in a message base class. When I have the following message.</p> <pre><code> [DataContract] public abstract class GatewayPageEvent:IDomainEvent { protected GatewayPageEvent() { On = DateTime.Now; } [DataMember(Order = 1)] public Guid GatewayPageId { get; set; } [DataMember(Order = 2)] public DateTime On { get; set; } } [DataContract] public class GatewayPageAddedToSite : GatewayPageEvent { [DataMember(Order = 3)]public string Url { get; set; } [DataMember(Order = 4)]public string SiteCode { get; set; } } </code></pre> <p>GatewayPageId is always deserializing as Guid.Empty. Here's a unit test I wrote that fails. I'm kinda stumped...</p> <pre><code> public string Serialize(object t) { var memoryStream = new MemoryStream(); ProtoBuf.Serializer.Serialize(memoryStream, t); return Convert.ToBase64String(memoryStream.ToArray()); } public object Deserialize(string value, Type targetType) { var bytes = Convert.FromBase64String(value); var stream = new MemoryStream(bytes); return ProtoBuf.Serializer.NonGeneric.Deserialize(targetType, stream); } [Test] public void protobuf_serialization_can_deserialized_guids() { var originalMessage = new GatewayPageAddedToSite {GatewayPageId = Guid.NewGuid(), SiteCode = "dls", Url = "test"}; var serializedMessage = Serialize(originalMessage); var @event = (GatewayPageAddedToSite)Deserialize(serializedMessage, typeof(GatewayPageAddedToSite)); Assert.AreEqual(@event.GatewayPageId, originalMessage.GatewayPageId); } </code></pre> <p>I know Guids work fine because the following unit test works just fine.</p> <pre><code>[Test] public void guids_work_fine() { var original = Guid.NewGuid(); var serialized = Serialize(original); var deserialized = (Guid) Deserialize(serialized, typeof (Guid)); Assert.AreEqual(original,deserialized); } </code></pre> <p>Am I defining my contract wrong? Or is this a problem with protobuf-net?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
