How to query for linked notes?

Question

I've got a method that will link an annotation to a sales order:

    /// <summary>   Links. </summary>
    /// <param name="noteGuid">         Unique identifier for the note. </param>
    /// <param name="salesOrderGuid">   Unique identifier for the sales order. </param>
    /// <returns>   A SalesOrder. </returns>
    public SalesOrder Link(Guid noteGuid, Guid salesOrderGuid)
    {
        var associateRequest = new AssociateRequest
                                   {
                                       Target =
                                           new EntityReference(
                                               SalesOrder.EntityLogicalName,
                                               salesOrderGuid),
                                       RelatedEntities =
                                           new EntityReferenceCollection
                                               {
                                                   new EntityReference(
                                                       Annotation
                                                           .EntityLogicalName,
                                                       noteGuid)
                                               },
                                       Relationship = new Relationship("SalesOrder_Annotation")
                                   };

        _xrmServiceContext.Execute(associateRequest);

        return GetSalesOrderByOrderGuid(salesOrderGuid);
    }

I am attempting to unit test this method with the following test:

    [Test]
    public void Link_ExistingRecordHavingNotes_LinksItemCorrectly()
    {
        using (var xrmServiceContext = new XrmServiceContext(_fakeOrganizationService))
        {
            // Arrange
            var salesOrderGuid = Guid.NewGuid();
            var note1 = new Annotation { Id = Guid.NewGuid(), Subject = "this is note1" };
            var salesOrder = new SalesOrder
                                 {
                                     Id = salesOrderGuid
                                 };

            _fakeContext.Initialize(new List<Entity> { salesOrder, note1 });

            this._fakeContext.AddRelationship(
                "SalesOrder_Annotation",
                new XrmFakedRelationship
                    {
                        Entity2LogicalName = "annotation",
                        Entity2Attribute = "salesorderid",
                        Entity1LogicalName = "salesorder",
                        Entity1Attribute = "SalesOrder_Annotation.Id",
                        RelationshipType = XrmFakedRelationship.enmFakeRelationshipType.OneToMany
                    });

            var sut = new SalesOrderService(xrmServiceContext);

            // Act
            var linkedRecord = sut.Link(note1.Id, salesOrderGuid);

            var annotations = xrmServiceContext.AnnotationSet.FirstOrDefault(note => note.ObjectId.Id == salesOrderGuid);

...

I am not understanding why annotations is null. When I link an entity to another entity using the above associate request, should it not link the 2 entities via ObjectId?

Answer 1

Annotations need to be created using a Create message with an explicit ObjectId property rather than with AssociateRequest.

Ex:

Then you will be able to query them.
