@SzymonPobiega so we really need all 3 outbox samples showing the same scenario? and does ef add any value when we have this https://docs.particular.net/samples/sqltransport-sqlpersistence/#receiver-project-accessing-the-ambient-database-details

I was thinking of consolidating them to one "outbox with sql" sample that uses sql transports and persistences. and remove the ef and point to the non-outbox ef code
