Sono stati importati più assembly con identità equivalente: "<assembly in-memory>" e "<assembly in memoria>"

Question

Viene visualizzato l'errore seguente quando si tenta di avviare il contenitore. Questa è una semplice applicazione web asp.net vnext. Sto provando ad ospitare questo container all'interno del docker in Windows Server 2016. Si prega di consulenza.

Answer 1

Tutti, dopo averlo seguito per un paio di giorni e più esperimenti. Ho ristretto. Il problema è che stavo cercando di spingere l'applicazione asp.net vnext solo con il framework dnx451. Dopo aver incluso il dnxcore50 ero in grado di spingere l'applicazione in finestra mobile contenitore all'interno di Windows Server 2016.
