Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/cache@v3, actions/checkout@v3, actions/setup-dotnet@v4, actions/setup-node@v3, actions/upload-artifact@v4, nuget/setup-nuget@v1. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Do not use Assert.Equal() to check for collection size. Use Assert.Single instead. (https://xunit.net/xunit.analyzers/rules/xUnit2013)
