Both examples create a service from a c# dotnet application.
Create a service using systemd.

The below yaml file copies all files from the local ./build/Release folder into the root of the snap. It installs all packages fro state-packages as dependencies that the service will require.
your-program-service-name.yaml
name: your-program-service-name
version: 0.1
summary: Your programs summary
description:
A description of what this service does
confinement: strict
apps:
your-program-service-name-searcher:
command: dotnet $SNAP/YourProgramName.dll
plugs: [network-bind]
daemon: simple
parts:
your-program-service-name-searcher-bin:
plugin: copy
files:
"./build/Release/*": "."
stage-packages:
- dotnet-runtime-8.0
- curl
To build the snap package run
snapcraft clean
mkdir -p build
snapcraft snap -o "$(pwd)/build/your-program-service-name.snap"
To install the snap without uploading to the Ubuntu snap store run
snap install "${pwd}/build/your-program-service-name.snap" --force-dangerous'
At this point, your c# console app should be running as a systemd service.
