NuGet package dependencies

July 3, 2026 · View on GitHub

Published packages are listed in build/packages.txt. That manifest includes src/ and ext/ library projects only — never toolchain/, plugins/, apps/, or other repo folders. All listed packages share the version in Directory.Build.props. Pack with pack.bat; see NUGET_RELEASE.md.

Arrows in the diagrams below point from a package to what it depends on.

Meta-package hierarchy

Meta-packages are dependency-only bundles (no source of their own). Pick the smallest tier that fits your app.

    SDK["Ara3D.SDK"]
  end

  subgraph tiers ["Meta-packages"]
    CORE["Ara3D.SDK.Core<br/>net8.0"]
    GEO["Ara3D.SDK.Geometry<br/>net8.0"]
    IO["Ara3D.SDK.IO<br/>net8.0-windows"]
    STUDIO["Ara3D.Studio.API"]
    WPF["Ara3D.Utils.Wpf<br/>ext/"]
  end

  SDK --> WPF

Meta-package	Directly includes
Ara3D.SDK.Core	Collections, DataTable, Events, F8, Logging, Memory, PropKit, Utils, Utils.Roslyn, WorkItems
Ara3D.SDK.Geometry	Collections, F8, Geometry, Memory, Models, Utils
Ara3D.SDK.IO	All I/O + BOS libraries, plus IfcLoader
Ara3D.SDK	Core + Geometry + IO + Studio.API + Utils.Wpf

Meta-package	TFM	Use when
Ara3D.SDK.Core	`net8.0`	Minimal cross-platform foundation
Ara3D.SDK.Geometry	`net8.0`	Meshes, models, SIMD math
Ara3D.SDK.IO	`net8.0-windows`	File formats, BOS, and IFC conversion
Ara3D.SDK	`net8.0-windows`	Everything above plus Studio API and WPF

Library dependency graph

Grouped by layer. Leaf nodes (no internal Ara3D dependencies): Collections, Events, F8, Memory, Utils, WorkItems, IO.SharpGLTF.

External NuGet dependencies

Most libraries have zero external NuGet deps. The exceptions:

  UtilsRoslyn["Utils.Roslyn"] --> CodeAnalysis["Microsoft.CodeAnalysis.CSharp"]
  UtilsRoslyn --> DiaSym["Microsoft.DiaSymReader.Native"]
  GltfExporter["IO.GltfExporter"] --> Newtonsoft["Newtonsoft.Json"]
  BOSIO["BimOpenSchema.IO"] --> ClosedXML
  BOSIO --> DuckDB["DuckDB.NET.Data.Full"]
  BOSIO --> Parquet["Parquet.Net"]

IfcLoader also ships the native web-ifc-library.dll from vendor/ (not a NuGet package).

Quick reference

If you need…	Reference
Minimal cross-platform foundation	`Ara3D.SDK.Core`
Meshes, SIMD math, models	`Ara3D.SDK.Geometry`
VIM, PLY, glTF, BOS, IFC	`Ara3D.SDK.IO`
Studio plug-in API	`Ara3D.Studio.API` (or full `Ara3D.SDK`)
WPF helpers	`Ara3D.Utils.Wpf`
Just one format	Individual package, e.g. `Ara3D.IO.VIM`

Per-project descriptions: src/README.md.

Not published to NuGet

Built locally but excluded from meta-packages and build/packages.txt. Projects under these folders set IsPackable=false (see toolchain/Directory.Build.props).

Folder	Examples	Notes
`toolchain/`	Parakeet, Plato, IfcTypeGen	Dev/codegen tools; Parakeet is not packed from this repo
`plugins/`	Bowerbird, Revit add-ins	Host plug-ins
`apps/`	BOS Browser	Standalone apps
