Exception while creating migration sql file

[gger]

Hi,
I'm getting exception while creating migration script using such command:
dotnet ef migrations script --startup-project MyApp --context MyAppContext --idempotent --no-transactions --output "MyApp.sql"

Exception first occured after upgrading project to .NET 6 and to newest devart library.

Thank you for your report. We will notify you when the issue is fixed.

The bug with generating the "Value cannot be null" error when adding or dropping FK via Code-First Migrations in EF Core is fixed. We will notify you when a new public build of dotConnect for Oracle is available for download.

The bug with generating the "Value cannot be null" error when dropping indexes via Code-First Migrations in EF Core is fixed in dotConnect for Oracle v9.16.1434.
