Minimal code project to recreate a nullreferenceexception thrown when executing migrations on devices for a Xamarin Android/iOS project.
Migrations generated using the following CLI commands from EFCoreMigrationIssue.Persistence (see https://github.com/ngrumbine/EFDemo for further details):
$> dotnet restore
$> dotnet ef -v migrations add <MigrationName> --startup-project ../DbConsole/
