Serializing F# Option types

Question

Consider the F# fragment below:

type MyType = {  
    CrucialProperty: int
    OptionalProperty: string option 
}

let first = { CrucialProperty = 500; Optio         


        

Answer 1

The FSharp.JsonSkippable library allows you to control in a simple and strongly typed manner whether to include a given property when serializing (and determine whether a property was included when deserializing), and moreover, to control/determine exclusion separately of nullability.
