Add support for MongoDB v4.0 for the MongoDB connector
The last version currently supported is 3.6
Brian Long commented
Trying to copy / archive data from CosmosDB (Mongo 3.6 API) with ADF and this 3.4 limitation is a real pain. CosmosDB has had the MongoDB 3.6 API since last February but we can't move to this version in production until ADF supports archive / restore with this version.
Archive / restore with CosmosDB 3.2 API still works as expected (thankfully).

What is the old connection string format?
The developer team wants to work with the new C#/.Net driver so they want to upgrade mongodb clusters to above v4.0 and I can't, with good conscious, tell them to delay the upgrade until ADF connector is officially supported. So I'm going to go ahead and run with the new version without full support.
I understand complete compatibility tests take time, but 3.4 is just too low.
Connecting to a MongoDB 4.0 cluster works with the old connection string format (as opposed to (mongo+srv) but official support from Microsoft would be great.
