dotnet-ado-patterns
Composable Azure DevOps YAML pipeline patterns for .NET projects: template references with extends, stages, jobs,
and steps keywords for hierarchical pipeline composition, variable groups and variable templates for centralized
configuration, pipeline decorators for organization-wide policy injection, conditional insertion with ${{ if }} and
${{ each }} expressions, multi-stage pipelines (build, test, deploy), and pipeline triggers for CI, PR, and scheduled
runs.
Version assumptions: Azure Pipelines YAML schema. DotNetCoreCLI@2 task for .NET 8/9/10 builds. Template
expressions syntax v2.
Scope
- Template references with extends, stages, jobs, and steps keywords
- Variable groups and variable templates for centralized configuration
- Pipeline decorators for organization-wide policy injection
- Conditional insertion with ${{ if }} and ${{ each }} expressions
- Multi-stage pipelines (build, test, deploy)
- Pipeline triggers for CI, PR, and scheduled runs
Out of scope
- Starter CI templates -- see [skill:dotnet-add-ci]
- CLI release pipelines (tag-triggered build-package-release for CLI tools) -- see [skill:dotnet-cli-release-pipeline]
- ADO-unique features (environments, service connections, classic releases) -- see [skill:dotnet-ado-unique]
- Build/test specifics -- see [skill:dotnet-ado-build-test]
- Publishing pipelines -- see [skill:dotnet-ado-publish]
- GitHub Actions workflow patterns -- see [skill:dotnet-gha-patterns]
Cross-references: [skill:dotnet-add-ci] for starter templates that these patterns extend,
[skill:dotnet-cli-release-pipeline] for CLI-specific release automation.
For detailed YAML examples (stage/job/step templates, extends, variable groups, conditional insertion, multi-stage
pipelines, triggers), see examples.md in this skill directory.
Agent Gotchas
- Template parameter types are enforced at compile time -- passing a string where
type: boolean is expected
causes a validation error before the pipeline runs; always match types exactly.
extends templates cannot be overridden -- callers cannot inject steps before or after the mandatory stages;
this is by design for policy enforcement.- Variable group secrets are not available in template expressions --
${{ variables.mySecret }} resolves at
compile time when secrets are not yet available; use runtime syntax instead.
