To protect potentially sensitive information in your connection string, you should move it out of source code. You can avoid scaffolding the connection string by using the Name= syntax to read it from configuration - see https://go.microsoft.com/fwlink/?linkid=2131148. For more guidance on storing connection strings, see https://go.microsoft.com/fwlink/?LinkId=723263.

Den gemeldeten Befehl dotnet ef dbcontext scaffold reproduzieren und den angeforderten Namen GaussDB.EntityFrameworkCore.PostgreSQL.Properties.GaussDBStrings.resources mit den in DotNetCore.EntityFrameworkCore.GaussDB eingebetteten Ressourcen vergleichen. Die im Stacktrace gezeigte GaussDBResources-Suche nachverfolgen; als erledigt gilt die Aufgabe, wenn das Scaffolding ohne MissingManifestResourceException abgeschlossen wird.
