SortedObservableCollectionAdaptor Avoiding Replace

[ccopsey]

Background: #640 (comment)

I just lost a day and half chasing down a very curious undesirable behaviour which I now realise was caused by the above. It took me that long to realise where the problem lied, and from there I could search for info and solutions.

Is there a reason why we can't add useReplaceForUpdates as an argument to the ISortedChangeSet flavour of Bind() in a similar manner to how it is implemented in ObservableCollectionAdaptor?

I am guaranteed to forget this episode and end up scratching my head for another day at some point in the (not too distant) future.

I would be happy to propose the PR.

You can probably make a feature request to add extra overload method or new method. It's a bit different to the issue you referenced which was a bug report. Roland is more likely to approve the idea of it if it's new functionality and a new method or overload.

That way in the issue you can coordinate how to design it.

In my mind it is an extra overload to Bind(), with an extra if-clause in case ChangeReason.Update. Very simple. But the amount of detail in that referenced comment, along with no apparent attempt to fix what looks to me to be simple, makes me question if I fully understand what I'm looking it.

I shall plough on and give it a go.
