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.

Code Navigation (Serena MCP)

Primary approach: Use Serena symbol operations for efficient code navigation:

1. Find definitions: serena_find_symbol instead of text search
2. Understand structure: serena_get_symbols_overview for file organization
3. Track references: serena_find_referencing_symbols for impact analysis
4. Precise edits: for clean modifications
