We are leaving Russia. We are against aggression and war with Ukraine. It is a tragedy for our nations, it is a nightmare

System.IO.FileLoadException

I installed hangfire server on .net 4.8. The job is to send data using a http client.
The hangfire server uses a .net 4.8 dll (api client wrapper) and that dll uses another dll .net standard 2.0 (api client) to send the data out.

I get an exception that it cannot find System.Text.Json Version 6.0.0.0

System.IO.FileLoadException

Kan bestand of assembly System.Text.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 of een van de afhankelijkheden hiervan niet laden. De manifestdefinitie van de gevonden assembly komt niet overeen met de assembly-verwijzing. (Uitzondering van HRESULT: 0x80131040)

I’m kind of stuck here, tried adding the system.text.json to all 3 projects but this doesnt make any differnce. Any idea why this is?
