We would like to use MongoDB with F#. There was a brief of prototype solution archived in github but was abandoned. The project I am talking about is https://github.com/mongodb-labs/mongo-fsharp-driver-prototype/pulse
This is an official request for F# driver.
AdminRachelle (Admin, MongoDB) shared this idea
It would be nice, if upstream is able to maintain just the F# records and unions serialisation parts at least.
