FunctionFoundry

CI.NETTestsCoverageBranch CoverageSkippedLicensePackages

FunctionFoundry is a modular collection of independent, production-grade .NET libraries that provide specialized capabilities not supplied by the BCL or common Microsoft packages.

Each library ships as its own DLL and NuGet package. There is no mandatory aggregate package and no shared runtime "commons" dependency between core packages. Nuget Packages: https://www.nuget.org/packages?q=functionfoundry

Packages

Each product has a dedicated README under src/<Package>/README.md describing exactly what it does.

FunctionFoundry.SecurityEnvelope encryption, HKDF key derivation, deterministic pseudonymization, threshold secret sharing, key-rotation planningREADME
FunctionFoundry.StorageTransactional file-set writes, content-addressed storage with GC, content-defined chunking, Merkle file-tree diffsREADME
FunctionFoundry.IntegrityCanonical JSON, hash manifests, Merkle proofs/multiproofs, tamper-evident hash chainsREADME
FunctionFoundry.ObservabilitySensitive-data redaction, event fingerprinting, adaptive sampling, burst coalescing, cardinality limitingREADME
FunctionFoundry.DataExternal merge sort, k-way sorted merge, structural tree diff, three-way merge, temporal interval joinREADME
FunctionFoundry.TextUnicode spoof detection, homoglyph normalization, secret scanning, near-duplicate indexing, delimited-text dialect inferenceREADME
FunctionFoundry.ResilienceAdaptive concurrency, hedged execution, execution budgets, checkpointed batch execution, retry budgetsREADME
FunctionFoundry.NetworkingResumable parallel downloads, Content-Range parsing, mirror selection, transfer planning, streaming integrity verificationREADME
FunctionFoundry.DistributedWeighted rendezvous hashing, version clocks, hybrid logical clocks, phi-accrual failure detection, quorum aggregationREADME
FunctionFoundry.SchedulingInterval-set algebra, recurring availability, business calendars, critical-path schedulingREADME

Requirements

  • .NET SDK 10.0.302 (pinned in global.json; roll-forward disabled)
  • Target framework: net10.0
  • C# 14.0

SDK versions receive explicit maintenance upgrades only. Do not silently change the pinned feature band.

Local dotnet pack produces *-local package versions by design. Release packs (CI or FF_RELEASE_PACK=true / publish workflow) omit the suffix.

Build

dotnet restore
dotnet build -c Release
dotnet test -c Release
dotnet pack -c Release

To produce a top-level Release/ folder with library binaries and NuGet packages:

# Linux / macOS
./build/publish-release.sh
# Windows
build\publish-release.cmd

Coverage (optional):

dotnet test -c Release --collect:"XPlat Code Coverage" --results-directory ./artifacts/test-results

Intermediate build outputs remain under artifacts/. Release deliverables are copied to Release/ (gitignored). Coverage breakdown: docs/coverage-summary.md.

Design principles

  • Specialized functions with nontrivial algorithms, protocols, or guarantees
  • Zero third-party runtime dependencies by default
  • Independent package consumption
  • Complete XML documentation
  • Deterministic builds and reproducible packages where the SDK supports it

FunctionFoundry
CI.NETTestsCoverageBranch CoverageSkippedLicensePackages
FunctionFoundry is a modular collection of independent, production-grade .NET libraries that provide specialized capabilities not supplied by the BCL or common Microsoft packages.
Each library ships as its own DLL and NuGet package. There is no mandatory aggregate package and no shared runtime "commons" dependency between core packages.
Nuget Packages: https://www.nuget.org/packages?q=functionfoundry
Packages
Each product has a dedicated README under src/<Package>/README.md describing exactly what it does.
PackagePurposeREADME
FunctionFoundry.SecurityEnvelope encryption, HKDF key derivation, deterministic pseudonymization, threshold secret sharing, key-rotation planningREADME
FunctionFoundry.StorageTransactional file-set writes, content-addressed storage with GC, content-defined chunking, Merkle file-tree diffsREADME
FunctionFoundry.IntegrityCanonical JSON, hash manifests, Merkle proofs/multiproofs, tamper-evident hash chainsREADME
FunctionFoundry.ObservabilitySensitive-data redaction, event fingerprinting, adaptive sampling, burst coalescing, cardinality limitingREADME
FunctionFoundry.DataExternal merge sort, k-way sorted merge, structural tree diff, three-way merge, temporal interval joinREADME
FunctionFoundry.TextUnicode spoof detection, homoglyph normalization, secret scanning, near-duplicate indexing, delimited-text dialect inferenceREADME
FunctionFoundry.ResilienceAdaptive concurrency, hedged execution, execution budgets, checkpointed batch execution, retry budgetsREADME
FunctionFoundry.NetworkingResumable parallel downloads, Content-Range parsing, mirror selection, transfer planning, streaming integrity verificationREADME
FunctionFoundry.DistributedWeighted rendezvous hashing, version clocks, hybrid logical clocks, phi-accrual failure detection, quorum aggregationREADME
FunctionFoundry.SchedulingInterval-set algebra, recurring availability, business calendars, critical-path schedulingREADME
Requirements
  • .NET SDK 10.0.302 (pinned in global.json; roll-forward disabled)
  • Target framework: net10.0
  • C# 14.0
SDK versions receive explicit maintenance upgrades only. Do not silently change the pinned feature band.
Local dotnet pack produces *-local package versions by design. Release packs (CI or FF_RELEASE_PACK=true / publish workflow) omit the suffix.
Build
dotnet restore
dotnet build -c Release
dotnet test -c Release
dotnet pack -c Release
To produce a top-level Release/ folder with library binaries and NuGet packages:
# Linux / macOS
./build/publish-release.sh
# Windows
build\publish-release.cmd
Coverage (optional):
dotnet test -c Release --collect:"XPlat Code Coverage" --results-directory ./artifacts/test-results
Intermediate build outputs remain under artifacts/. Release deliverables are copied to Release/ (gitignored). Coverage breakdown: docs/coverage-summary.md.
Design principles
  • Specialized functions with nontrivial algorithms, protocols, or guarantees
  • Zero third-party runtime dependencies by default
  • Independent package consumption
  • Complete XML documentation
  • Deterministic builds and reproducible packages where the SDK supports it

About
Modular .NET 10 libraries for specialized engineering problems: envelope crypto, transactional storage, integrity proofs, adaptive observability, conflict-aware data processing, text risk analysis, resilience, resumable HTTP transfers, distributed algorithms, and scheduling, each package independent, zero mandatory commons.
