Create a service definition file:

Sudo nano / etc / systemd / system / Kestrel hellomvc.service
The following is an example of a service application file:

[Unit]
Description=Example .NET Web API App running on Ubuntu
 
[Service]
WorkingDirectory=/var/aspnetcore/hellomvc
ExecStart=/usr/bin/dotnet /var/aspnetcore/hellomvc/hellomvc.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
SyslogIdentifier=dotnet-example
User=xxx
Environment=ASPNETCORE_ENVIRONMENT=Development
 
[Install]
WantedBy=multi-user.target
Save the file and enable the service.

systemctl enable kestrel-hellomvc.service
Start the service and verify that it is running.

systemctl start kestrel-hellomvc.service
systemctl status kestrel-hellomvc.service
You need to use the application dll path of the working directory (the path to your application and Exec Start) is set to the folder. By default, this is enough.
