Определение DbUpdate

public class DbUpdate 
{ 
    public long UniqueId { get; set; } 
    public string UpdateMethodName { get; set; } 
    public DateTime? UpdateStart { get; set; } 
    public DateTime? UpdateEnd { get; set; } 
    public DbUpdateState DbUpdateState { get; set; } 
}

Код фактического сообщения:

 var dbUpdate1 = new DbUpdate() 
     { 
      UpdateMethodName = "abc.def", 
      UpdateStart = new DateTime(2014, 10, 24, 15, 30, 23), 
      UpdateEnd = null, 
      DbUpdateState = DbUpdateState.Running 
     }; 

     long dbUpdate1UniqueId = dbUpdateRepository.CreateDbUpdate(dbUpdate1); 

     var dbUpdates = dbUpdateRepository.GetAllDbUpdates().ToList();

класс репо, который содержит методы, вызываемые из тестового кода:

public class DbUpdateRepository: IDbUpdateRepository 
{ 
    readonly IGraphClient graphClient; 
    readonly IMyStoryUserPrincipal principal; 
    readonly IMyStoryUniqueIdGenerator uniqueIdGenerator; 

    public DbUpdateRepository (
     IMyStoryUserPrincipal principal, 
     IGraphClient graphClient, 
     IMyStoryUniqueIdGenerator uniqueIdGenerator) 
    { 
     this.principal = principal; 
     this.graphClient = graphClient; 
     this.uniqueIdGenerator = uniqueIdGenerator; 
    } 

    public IEnumerable<DbUpdate> GetAllDbUpdates() 
    { 
     var query = graphClient 
      .RootNode 
      .StartCypher("root") 
      .Match("root-[:" + HasDbUpdates.TypeKey + "]-dbUpdates") 
      .Return(dbUpdates => dbUpdates.As<DbUpdate>()); 

     return query.Results;  <<<<< exception thrown here 
    } 


    public long CreateDbUpdate (DbUpdate dbUpdate) 
    { 
     dbUpdate.UniqueId = uniqueIdGenerator.NextDbUpdateId(); 

     graphClient.Create(dbUpdate, 
          new HasDbUpdates(graphClient.RootNode) 
          { 
           Direction = RelationshipDirection.Incoming 
          }); 

     return dbUpdate.UniqueId; 
    } 
}

Оказывается, что Neo4jClient не может справиться с DateTime. Вы должны использовать DateTimeOffset.
