Migrate to Centralized NuGet Package Management (CPM)

[Copilot]

Migrates package version management from per-project Version attributes to NuGet's Centralized Package Management, consolidating all versions into a single source of truth.

Changes

• Directory.Packages.props (new): Enables CPM via <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>; declares all 11 package versions alphabetically
• All .csproj files: Removed Version="..." from every <PackageReference> — all other attributes (PrivateAssets, etc.) preserved
• Ressy.sln: Added Directory.Packages.props as a solution item under Misc

Before:

<PackageReference Include="FluentAssertions" Version="8.8.0" />
<PackageReference Include="xunit" Version="2.9.3" />

After (Directory.Packages.props):

<PackageVersion Include="FluentAssertions" Version="8.8.0" />
<PackageVersion Include="xunit" Version="2.9.3" />

After (.csproj):

<PackageReference Include="FluentAssertions" />
<PackageReference Include="xunit" />

No packages had conflicting versions across projects.

Original prompt

Migrate to Centralized NuGet Package Management (CPM)

Migrate the repository from per-project Version attributes on <PackageReference> to NuGet's Centralized Package Management (CPM).

What to do

1. Create a Directory.Packages.props file at the root of the repository with <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally> and a <PackageVersion> entry for every unique package used across all .csproj files. Use the version already present in the .csproj files.

2. Update all .csproj files to remove the Version="..." attribute from every <PackageReference> element (CPM now manages the version centrally). Keep all other attributes (e.g. PrivateAssets, Condition, ExcludeAssets, etc.) intact.

3. Add Directory.Packages.props to the .sln file as a solution item, typically under a Solution Items folder, so it is visible and accessible from within the solution.

4. Run dotnet build at the end to catch and fix any formatting or structural issues introduced during the migration.

5. Do not change any TargetFramework(s), project structure, or anything unrelated to package versioning.

Notes

• If a package appears with different versions in different projects, use the highest version and make a note in the PR description.
• <PackageVersion> entries in Directory.Packages.props should be sorted alphabetically.
• Make sure the file includes a valid MSBuild props file <Project> root element.
• Preserve all Condition attributes on <PackageReference> elements.
