TaskResultBuilder ? about taskbuilder.fs HOT 3 CLOSED

I think you can write your own pretty easily without getting into the guts of task handling, just by wrapping TaskBuilder. For now, I recommend going that route.

e.g.

type TaskResultBuilder() =
     member this.Bind
          ( resultTask : Result<'ok, 'err> Task
          , onOk : 'ok -> Task<Result<'out, 'err>>
          ) : Task<'out, 'err>> =
          task {
              let! maybe = resultTask
              match maybe with
              | Ok yep -> return! onOk yep
              | Error e -> return Error e
          }
    member this.Return(x) = Task.FromResult(Ok x)

Hi @rspeele, yes I can write my own TaskResultBuilder (I currently do it in my few projects) but just I need to copy the file to all of my projects which uses Task+Result. so just wondering if I can use any other thirth party lib instead I do myself (especially I am using your TaskBuilder) :-)

I recommend publishing your own wrapper (that you mentioned you're currently using) as a NuGet package. If you don't want it to be a big thing, you can use a local feed.
