[Service]
WorkingDirectory=/var/www/SERVICE_NAME
ExecStart=/usr/bin/dotnet  /var/www/SERVICE_NAME/SERVICE_NAME.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=SERVICE_NAME-app

In Source Code Management choose Git and enter details.

Select GitHub hook trigger for GITScm polling from Build Triggers.

Click Add Build Step > Execute Shell and write shell details as shown in below.

_{-p:RunAnalyzers=false is added on this example because my service is getting built very slow.}

Save changes and move to the next step.

Enable webhook on your GitHub repository settings. Use your {Jenkins IP}:8080

After you push a new commit on selected branch, Jenkins should build your .NET application and publish it.

Check your service status with:
