description: 'Ready-to-use prompts for comprehensive .NET framework upgrade analysis and execution'

Project Discovery & Assessment

• name: "Project Classification Analysis"

prompt: "Identify all projects in the solution and classify them by type (`.NET Framework`, `.NET Core`, `.NET Standard`). Analyze each `.csproj` for its current `TargetFramework` and SDK usage."

• name: "Dependency Compatibility Review"

prompt: "Review external and internal dependencies for framework compatibility. Determine the upgrade complexity based on dependency graph depth."

• name: "Legacy Package Detection"

prompt: "Identify legacy `packages.config` projects needing migration to `PackageReference` format."

Upgrade Strategy & Sequencing

• name: "Project Upgrade Ordering"

prompt: "Recommend a project upgrade order from least to most dependent components. Suggest how to isolate class library upgrades before API or Azure Function migrations."

• name: "Incremental Strategy Planning"

prompt: "Propose an incremental upgrade strategy with rollback checkpoints. Evaluate the use of **Upgrade Assistant** or **manual upgrades** based on project structure."

• name: "Progress Tracking Setup"

prompt: "Generate an upgrade checklist for tracking build, test, and deployment readiness across all projects."

Framework Targeting & Code Adjustments

• name: "Target Framework Selection"

prompt: "Suggest the correct `TargetFramework` for each project (e.g., `net8.0`). Review and update deprecated SDK or build configurations."

• name: "Code Modernization Analysis"

prompt: "Identify code patterns needing modernization (e.g., `WebHostBuilder` → `HostBuilder`). Suggest replacements for deprecated .NET APIs and third-party libraries."

• name: "Async Pattern Conversion"

prompt: "Recommend conversion of synchronous calls to async where appropriate for improved performance and scalability."

NuGet & Dependency Management

• name: "Package Compatibility Analysis"

prompt: "Analyze outdated or incompatible NuGet packages and suggest compatible versions. Identify third-party libraries that lack .NET 8 support and provide migration paths."

• name: "Shared Dependency Strategy"

prompt: "Recommend strategies for handling shared dependency upgrades across projects. Evaluate usage of legacy packages and suggest alternatives in Microsoft-supported namespaces."

• name: "Transitive Dependency Review"

prompt: "Review transitive dependencies and potential version conflicts after upgrade. Suggest resolution strategies for dependency conflicts."

CI/CD & Build Pipeline Updates

• name: "Pipeline Configuration Analysis"

prompt: "Analyze YAML build definitions for SDK version pinning and recommend updates. Suggest modifications for `UseDotNet@2` and `NuGetToolInstaller` tasks."

• name: "Build Pipeline Modernization"

prompt: "Generate updated build pipeline snippets for .NET 8 migration. Recommend validation builds on feature branches before merging to main."

• name: "CI Automation Enhancement"

prompt: "Identify opportunities to automate test and build verification in CI pipelines. Suggest strategies for continuous integration validation."

Testing & Validation

• name: "Build Validation Strategy"

prompt: "Propose validation checks to ensure the upgraded solution builds and runs successfully. Recommend automated test execution for unit and integration suites post-upgrade."

• name: "Service Integration Verification"

prompt: "Generate validation steps to verify logging, telemetry, and service connectivity. Suggest strategies for verifying backward compatibility and runtime behavior."

• name: "Deployment Readiness Check"

prompt: "Recommend UAT deployment verification steps before production rollout. Create comprehensive testing scenarios for upgraded components."

Breaking Change Analysis

• name: "API Deprecation Detection"

prompt: "Identify deprecated APIs or removed namespaces between target versions. Suggest automated scanning using `.NET Upgrade Assistant` and API Analyzer."

• name: "API Replacement Strategy"

prompt: "Recommend replacement APIs or libraries for known breaking areas. Review configuration changes such as `Startup.cs` → `Program.cs` refactoring."

• name: "Regression Testing Focus"

prompt: "Suggest regression testing scenarios focused on upgraded API endpoints or services. Create test plans for critical functionality validation."

Version Control & Commit Strategy

• name: "Branching Strategy Planning"

prompt: "Recommend branching strategy for safe upgrade with rollback capability. Generate commit templates for partial and complete project upgrades."

• name: "PR Structure Optimization"

prompt: "Suggest best practices for creating structured PRs (`Upgrade to .NET [Version]`). Identify tagging strategies for PRs involving breaking changes."

• name: "Code Review Guidelines"

prompt: "Recommend peer review focus areas (build, test, and dependency validation). Create checklists for effective upgrade reviews."

Documentation & Communication

• name: "Upgrade Documentation Strategy"

prompt: "Suggest how to document each project's framework change in the PR. Propose automated release note generation summarizing upgrades and test results."

• name: "Stakeholder Communication"

prompt: "Recommend communicating version upgrades and migration timelines to consumers. Generate documentation templates for dependency updates and validation results."

• name: "Progress Tracking Systems"

prompt: "Suggest maintaining an upgrade summary dashboard or markdown checklist. Create templates for tracking upgrade progress across multiple projects."

Tools & Automation

• name: "Upgrade Tool Selection"

prompt: "Recommend when and how to use: `.NET Upgrade Assistant`, `dotnet list package --outdated`, `dotnet migrate`, and `graph.json`
