Inizia riproducendo il problema con F5 in un progetto client interattivo Blazor WebAssembly usando C# extension 2.140.8, quindi raccogli i log di traccia descritti in SUPPORT.md e ispeziona il flusso di avvio e debug dell’estensione. L’attività è completata quando il server di sviluppo si avvia, Chrome o Chromium si apre e i breakpoint WebAssembly si collegano come previsto.
