ln-712-nuget-upgrader

Type: L3 Worker Category: 7XX Project Bootstrap Parent: ln-710-dependency-upgrader

Upgrades .NET NuGet packages with automatic breaking change detection and migration.

Overview

AspectDetails
InputSolution/project path
OutputUpdated .csproj files, migration report
Supports.NET 6, 7, 8, 9, 10

Workflow

See diagram.html for visual workflow.

Phases: Pre-flight → Find Projects → Security Audit → Check Outdated → Identify Breaking → Apply Upgrades → Restore & Build → Report

Phase 0: Pre-flight Checks

CheckRequiredAction if Missing
.csproj file(s)YesBlock upgrade
.sln fileNoUse csproj discovery instead

Workers assume coordinator (ln-710) already verified git state and created backup.

Phase 1: Find Projects

Discovery Methods

MethodCommand
Find .csprojGet-ChildItem -Recurse -Filter *.csproj
From solutiondotnet sln list

Phase 2: Security Audit

Commands

CheckCommand
Vulnerable packagesdotnet list package --vulnerable
Outdated packagesdotnet list package --outdated

Actions

SeverityAction
CriticalBlock upgrade, report
HighWarn, continue
Moderate/LowLog only

Phase 3: Check Outdated

Using dotnet-outdated

StepCommand
Install tooldotnet tool install --global dotnet-outdated-tool
Checkdotnet outdated --output json

Phase 4: Identify Breaking Changes

Detection

  1. Compare current vs latest major versions
  2. Check breaking_changes_patterns.md
  3. Use MCP tools (see below) for migration guides

Common Breaking Changes

PackageBreaking VersionKey Changes
Microsoft.EntityFrameworkCore8 → 9Query changes, migration format
Serilog.AspNetCore7 → 8Configuration format
Swashbuckle.AspNetCore6 → 7Minimal API support

MCP Tools for Migration Search

Priority Order (Fallback Strategy)

PriorityToolWhen to Use
1mcp__context7__query-docsFirst choice for library docs
2mcp__Ref__ref_search_documentationOfficial Microsoft docs
3WebSearchLatest info, community solutions

Context7 Usage

StepToolParameters
1. Find librarymcp__context7__resolve-library-idlibraryName: "EntityFrameworkCore"
2. Query docsmcp__context7__query-docsquery: "EF Core 8 to 9 migration breaking changes"

MCP Ref Usage

ActionToolQuery Example
Searchmcp__Ref__ref_search_documentation"dotnet EntityFrameworkCore 9 migration guide"
Readmcp__Ref__ref_read_urlURL from search results

WebSearch Fallback

Use when Context7/Ref return no results:

  • "<package> .NET <version> breaking changes migration"
  • "<error code> <package> fix"

Phase 5: Apply Upgrades

Priority Order

PriorityPackage Type
1SDK/Runtime (Microsoft.NET.Sdk)
2Framework (Microsoft.AspNetCore.*)
3EF Core (affects migrations)
4Logging (Serilog.*)
5Other packages

Commands

ActionCommand
Update specificdotnet add package <name> --version <ver>
Update alldotnet outdated --upgrade

Phase 6: Restore & Build

Commands

StepCommand
Restoredotnet restore
Builddotnet build --configuration Release
Testdotnet test

On Failure

  1. Identify failing package from error
  2. Search Context7/Ref for migration guide
  3. If unresolved: rollback package, continue

Phase 7: Report Results
