GetBuiltProjectOutput Errore di esecuzione di Xamarin Forms per iOS su Visual Studio

Question

Sembra che si verifichi questo strano problema durante l'esecuzione di Xamarin.iOS su Visual Studio. Questo è successo dopo che ho aggiornato all'ultima Xamarin (oggi).

Ho collegato al mio Mac però. Ho cercato di Google che, nessuna risposta ...

"Errore MSB4057: Il bersaglio 'GetBuiltProjectOutputRecursive' non esiste nel progetto"

Qual è il problema? Prima dell'aggiornamento, ha funzionato!

Answer 1

Ho risolto il problema sulla mia installazione.

Ecco quello che ho fatto:

1. installare la più nuova Xamarin sia Visual Studio e mac.
2. Installare xamarin studio (più recente)
3. Rimuovere tutti i prodotti xamarin incluso gtk.
4. Installare Xamarin più recente (pacchetto completo) con il programma di installazione
5. Riavviare il pc
6. Apri soluzione e pulito/costruire
