Unable to get tab completion to work

I created a simple DragonFruit console app, then followed the instructions in https://github.com/dotnet/command-line-api/wiki/dotnet-suggest (and resolved the execution policy issues in 64- and 32-bit) then I opened a "Developer Powershell" from Visual Studio, change directory to where the exe is and typed `.\DragonFruit --f` (my Main method has an `int foo` argument) however it did not autocomplete (instead nothing happens). Things like `.\DragonFruit -h` work as expected. Also `$availableToComplete` is given a value during startup, namely "dotnet-suggest\ndotnet suggest".

How can I debug this?

El informe menciona una aplicación de consola DragonFruit, el comando .\DragonFruit --f, Developer PowerShell y dotnet-suggest; comienza reproduciendo ese comando y siguiendo el recorrido de completion. También se informa del valor $availableToComplete, así que compara ese estado inicial con el comportamiento de completion que falla. Se considera completado cuando se identifica el fallo o el prerrequisito que falta para la completion de la opción indicada.
