Convert .NET projects and solutions (.sln, .slnx) to NuGet Central Package Management (CPM) using Directory.Packages.props. USE FOR: converting to CPM, centralizing or aligning NuGet package versions across multiple projects, inlining MSBuild version properties from Directory.Build.props into Directory.Packages.props, resolving version conflicts or mismatches across a solution or repository, updating or bumping or syncing package versions across projects. Also activate when packages are out of s

I want to convert my repository at `./old-net-app` to Central Package Management. The project contains legacy `packages.config` files alongside newer project files. Please run the migration.

Convert to Central Package Management

Centralize package versions in Directory.Packages.props while preserving project behavior and producing reviewable before/after evidence.

Choose a mode first

Do this before running builds or changing files.

Guard mode -- If any in-scope project uses packages.config, stop. Explain that CPM requires PackageReference and recommend migrating first. Do not create or modify files.
Package-maintenance mode -- A request to update, align, bump, or sync packages authorizes those package edits, not CPM conversion. Audit the named scope, resolve the requested versions, update existing project/shared version declarations, and restore/build every affected CLI target from the directory that establishes its applicable global.json. Ask only when the version or alignment policy is ambiguous. Do not create or modify Directory.Packages.props, remove versions for CPM, or capture conversion artifacts. Complete the package work, then recommend CPM as the durable follow-up.
Conversion mode -- Use only when the user explicitly asks to adopt, enable, or convert to CPM. Follow the workflow below.

If the scope is unclear, ask once before proceeding.

Default execution plan

Guard: use a minimal scoped detection pass, then answer and stop.
Package maintenance: use a compact audit, edit only the requested package versions in their existing locations, validate affected targets, then recommend CPM. Do not read conversion references or enter the conversion workflow.
Conversion: batch the preflight, baseline, audit/mutation, final validation, and report work to avoid redundant turns. Revisit a stage only when new CPM-specific evidence requires a targeted follow-up.

This plan is an efficiency default, not a hard cap. Never omit an in-scope project, imported .props/.targets file, detected complexity, required validation, or deliverable to save a turn. Batch complete work where practical.

Inputs

Input	Required	Rule
Scope	Yes	Project, solution, or directory containing the projects to inspect or convert
Conflict strategy	For package maintenance or conversion with conflicts	If the user already supplied a strategy such as "use the highest version," apply it without asking again and record its impact. Otherwise stop after the audit and ask before editing.

Read references only when needed

Never preload all references.

Condition	Read
Entering conversion baseline or producing the package diff	baseline-comparison.md
A conflict, conditional reference, shared import, security concern, or `VersionOverride` is detected	audit-complexities.md
Placement is unclear or conditional `PackageVersion`/`VersionOverride` is required	directory-packages-props.md
A package version uses an MSBuild property	msbuild-property-handling.md
Restore or build fails after conversion	validation-and-errors.md
