Inizia da src/Microsoft.ML.ModelBuilder/VsProjectSystem.cs:85 e segui la chiamata da src/Microsoft.ML.ModelBuilder/ViewModels/ConsumeViewModel.cs:307. Riproduci il flusso Consume scegliendo Add console app, quindi analizza l'errore relativo alla chiamata Visual Studio DTE GetFileName. Il lavoro è completato quando l'applicazione console viene aggiunta alla soluzione senza il popup di errore.
