Unexpected behavior of JoinOperator MatchFirstRowUsingCrossApply: ignores EntityAlias and returns columns in PascalCase

[jordimontana82]

Not sure if this is the best repo, but when playing with one of the newer join operators, the query below ignores the EntityAlias of the LinkEntity and also returns the column name in Pascal Case ("Name") as opposed to "name".

This is different to the behaviour of other join types (i.e. inner or left outer).

Is this expected?

                ColumnSet = new ColumnSet("firstname")
            };

            var linkedEntity = new LinkEntity(
                        linkFromEntityName: "contact",
                        linkToEntityName: "account",

            linkedEntity.EntityAlias = "account";
            query.LinkEntities.Add(linkedEntity);

            var result = _service.RetrieveMultiple(query);
            Assert.Single(result.Entities);
            Assert.Equal("Joe", result.Entities[0]["firstname"]);
            Assert.Equal("Contoso", result.Entities[0]["account.name"]); //Fails as it just returns the value in a "Name" attribute
        }
