We would like to use MongoDB with F#. There was a brief of prototype solution archived in github but was abandoned, were there any reasons why?

Also why isn't F# DUs and records supported by default?

The project I am talking about is https://github.com/mongodb-labs/mongo-fsharp-driver-prototype/pulse

• If there are no plans for an F# driver, how much of the prototype driver is salvagable to make it work with current mongo driver C#?
