Eigenschaften, die im Schattenstaat erstellt werden, obwohl Eigentum im Unternehmen vorhanden ist [Duplikat] ⇐ C#

[Anonymous]

Ich habe Probleme mit Efcore. Ich habe einige Einheiten mit Navigationseigenschaften erstellt. Ich werde unten ein Beispiel unten veröffentlichen (SystemLicense und Kunde). Diese haben eine Weile gut gearbeitet, aber ich musste die Ondelete-Actions so ändern, dass sie dem tatsächlichen Workflow entspricht. Also habe ich die Beziehungen mit Fluent konfiguriert. Das Problem: Bei der Erstellung einer neuen Migration, um diese Änderungen widerzuspiegeln, werden mehrere Eigenschaften im Schattenzustand erzeugt. In diesem Beispiel schafft es CustomerID als CustomerID1, obwohl es soweit ich sehen kann. Dies ist das vollständige Migrationsprotokoll (findet für einige Modelle statt, ich habe andere Protokolleinträge in Bezug auf andere Modelle entfernt) < /p>

Ich habe bereits versucht, die DataAttributes im Modell direkt ohne Wirkung festzulegen. Ich habe beide versucht, in der Konfiguration "HasconstraintName ()" hinzugefügt und zu entfernen, beide ohne Änderungen.>
