Swagger settings for FSharp.SystemTextJson. Still experimantal


Only replace AddSwaggerGen with AddSwaggerForSystemTextJson

let builder =  WebApplication.CreateBuilder(args)
let fsOptions = JsonFSharpOptions() // setup options here 
//setup usage of JsonFSharpConverter                
                    .AddJsonOptions(fun opts ->
// setup usage of SwaggerForSystemTextJson - use instead AddSwaggerGen 
let app = builder.Build()
if (app.Environment.IsDevelopment()) then
      app.UseSwagger() |> ignore
      app.UseSwaggerUI() |> ignore

What works

Not everything is now implemented. Some things works with limitations


  • Works
  • All properties are required except of Skippable
  • Option properties are set as nullable


  • Works
  • Evaluates to array of composed type
  • Array has length limits to tuple length
  • Composed type is made as oneOf keyType and valueType
  • Warning - request generated by this schema could be invalid.


  • List and Set: works
  • Maps
    • with string keys - works
    • with boxed string - works
    • other - works
      • Evaluates to array of Tuples.
      • Warning - request generated by this schema could be invalid
