How can i create a Service for a dotnet application

I need help to create a service for a aspnetcore application on linux. I developed and created a app which runs when i start it with ./Application. But if I create a Service it fails.

Status results in:

Service is working fine, but your application is throwing an error itself.

Run journalctl -u alphabot -f, restart service and watch the terminal. It might be a busy port, config file...
