Research direction

Open Directory.Packages.props and compare the listed package versions with the issue’s package table and project-reference grep results. Remove only the nine unused PackageVersion entries, then run dotnet build; done means the entries are gone and the build still succeeds.

Written by the indexing model from the issue text.

Description

chore needs triage tech-debt

What

Remove NuGet packages declared in Directory.Packages.props that have zero project references and zero code usage. Verified by grepping PackageReference Include="<pkg>" across all .csproj/.fsproj files.

Packages to remove

Package	Version
`MessagePack`	2.5.302
`KubernetesClient`	19.0.2
`Riok.Mapperly`	4.2.1 — Generator.Equals already handles equality codegen
`Samboy063.Tomlet`	6.0.0 — second TOML parser; Tomlyn is the one actually used
`TUnit`	0.25.21 — suite runs entirely on xunit.v3
`Github.Actions.Core`	9.0.0
`Amazon.Lambda.APIGatewayEvents`	2.7.1
`Amazon.Lambda.AspNetCoreServer.Hosting`	1.9.0
`Aspire.Hosting`	13.4.3 — bare meta-package; only `Aspire.Hosting.AppHost` is referenced

How

Delete each <PackageVersion> entry from Directory.Packages.props. Run dotnet build to confirm nothing breaks.
