Example for Github Action Deploy Pipeline

This is an example of how to configure a git repo to build, restore and test a project when changes are pushed to it. Create a .github\workflows folder and place the build.yml file in it.

Step Overview

Step	What it does
Checkout	Clones the repository into the runner so subsequent steps have access to the source code.
Setup .NET	Installs the specified .NET SDK version on the runner.
Restore dependencies	Runs dotnet restore to download all NuGet packages defined in the solution.
Build	Compiles the solution in Release configuration, skipping restore since it already ran.
Test	Runs all test projects in Release mode without rebuilding, and writes results to a .trx file.
Upload test results	Uploads the .trx file as a workflow artifact so results are accessible in the GitHub Actions UI. Runs even if tests fail (if: always()).
