Issue Description

PS Class with using module statement throws type not found. If in the integrated PS console I run using module X and then remove and add back the using statements the error will away.

It looks as though VS code is not running the using statements while editing the script.

Expected Behaviour

Open a class file with types residing in a module and no type not found error is thrown.

Actual Behaviour

Type not found until manually running using statements in integrated console.

Attached Logs

Follow the instructions in the troubleshooting docs
about capturing and sending logs.

Iniziare dalla documentazione di troubleshooting e riprodurre il problema aprendo un file di classe i cui tipi provengono da un modulo. Confrontare il comportamento del file di classe con l'esecuzione di using module X nella console PowerShell integrata; il lavoro è completato quando l'errore di tipo non trovato non compare più senza rieseguire manualmente le using statements.
