Beim Aktualisieren von Projekten mit Nuget-Paketen von Vx20XX auf VS2015 liegt möglicherweise ein Problem mit Nuget-Paketen vor.
Beispiel für eine Fehlermeldung: Dieses Projekt verweist auf NuGet-Pakete, die auf diesem Computer fehlen. Aktivieren Sie die NuGet-Paketwiederherstellung, um sie herunterzuladen.
Update 06.02.2016: Ich hatte einen Link zu den Informationen, aber es funktioniert nicht mehr. Ich vermute, dass ein neuer Weg das Problem gelöst hat ???
Ich habe mein Problem beim Schreiben eines kleinen Programms behoben, das eine MSBuild-integrierte Paketwiederherstellung im Vergleich zur automatischen Paketwiederherstellung ausführt
Sie können die ausführbare Datei des Tools hier herunterladen .
Bitte lassen Sie mich das Ergebnis wissen :-)!
