Sync Framwork custom implementation RRS feed

  • Question

  • Hi, i'm trying to understand Microsofts Syncronization FrameWork. So far i have undestand some important issues, but i read about that the tick count for replica can be the local clock, im implementing the GetNextTickCount() method like

    return (ulong) DateTime.UtcNow.Ticks;

    im adding existing contacts, and logically the version of creation can be the time of creation + idreplica.

    Everything goes as planned until the sinchronization begins... the i get the error

    "A version was not contained in a knowledge instance as expected."

    When i see the Knowledge is says [0:0].

    How i can solve this..??

  • Hi,


    Do you have the call stack where you see this error? It may help us find the cause. Are you setting Knowledge.SetLocalTickCount(DateTime.UtcNow.Ticks) on each provider before starting the sync session?

    And yes, every time i call to Sinchronize() method i set
    But when debugging the localProvider.ReplicaMetadata.GetKnowledge() says Scope[0:0]...

    In MyReplica class im using an internal ReplicaMetadata object...
            public SyncKnowledge GetKnowledge()
                if (replicaMetadata == null) throw new NullReferenceException("The internal Metadata is null.");
                return replicaMetadata.GetKnowledge();

    thnx in advanced...

    I'm not sure why your local tick count is not reflected in your knowledge even though you seem to be setting it. Is is possible for you to share your project so I can debug?
