如何使F#长颈鹿默认路径指向/健康?

我有以下几点 Program.fs

let webApp = choose [ setStatusCode 404 >=> text "Not Found" ]

let errorHandler (ex : Exception) (logger : ILogger) =
    logger.LogError(ex, "An unhandled exception has occurred while executing the request.")
    clearResponse >=> setStatusCode 500 >=> text ex.Message

let configureApp (app : IApplicationBuilder) =
    app.UseHealthChecks(PathString("/health")) |> ignore
    let env = app.ApplicationServices.GetService<IHostingEnvironment>()
    (match env.IsDevelopment() with
    | true  -> app.UseDeveloperExceptionPage()
    | false -> app.UseGiraffeErrorHandler errorHandler)
        .UseHttpsRedirection()
        .UseStaticFiles()
        .UseGiraffe(webApp)

let configureServices (services : IServiceCollection) =
    services.AddHealthChecks() |> ignore
    services.AddCors()    |> ignore
    services.AddGiraffe() |> ignore

let configureLogging (builder : ILoggingBuilder) =
    builder.AddFilter(fun l -> l.Equals LogLevel.Error)
           .AddConsole()
           .AddDebug() |> ignore

[<EntryPoint>]
let main _ =
    let contentRoot = Directory.GetCurrentDirectory()
    let webRoot     = Path.Combine(contentRoot, "WebRoot")
    WebHostBuilder()
        .UseKestrel()
        .UseContentRoot(contentRoot)
        .UseIISIntegration()
        .UseWebRoot(webRoot)
        .Configure(Action<IApplicationBuilder> configureApp)
        .ConfigureServices(configureServices)
        .ConfigureLogging(configureLogging)
        .Build()
        .Run()
    0

我希望默认端点以健康检查为目标(即。 /health
