Composable GitHub Actions workflow patterns for .NET projects: reusable workflows with workflow_call, composite actions for shared step sequences, matrix builds across TFMs and operating systems, path-based triggers, concurrency groups for duplicate run cancellation, environment protection rules, NuGet and SDK caching strategies, and workflow_dispatch inputs for manual triggers.

Version assumptions: GitHub Actions workflow syntax v2. actions/setup-dotnet@v4 for .NET 8/9/10 support. actions/cache@v4 for dependency caching.
