Version 1.1

• #141: Add fluent options builder. JsonFSharpOptions has the following new methods:

  • static methods that create options with default settings: .Default(), .NewtonsoftLike(), .FSharpLuLike() and .ThothLike().
  • instance methods .WithOptionAbc(?bool) for each flag JsonUnionEncoding.Abc, that sets or unsets this option and returns a new JsonFSharpOptions.
  • instance methods .WithAbc(value) for each optional argument abc of its constructor, that sets this option and returns a new JsonFSharpOptions.
  • an instance method .ToJsonSerializerOptions() that returns a new JsonSerializerOptions with the corresponding JsonFSharpConverter configured.
  • an instance method .AddToJsonSerializerOptions(options) that takes an existing JsonSerializerOptions, configures the corresponding JsonFSharpConverter and returns unit.

  The above is now the recommended way of configuring the library, and future options may be only made available using fluent methods and not using constructor arguments.

• #146: Add option .WithSkippableOptionFields(?bool) that makes fields of type option and voption behave like Skippable: None / ValueNone is represented by a missing field instead of a null value.

  This is equivalent to the pre-1.0 default behavior, and is now recommended if this behavior is desired instead of IgnoreNullValues = true or DefaultIgnoreCondition = WhenWritingNull.
