DotNetWorkQueue.Aq.ExpressionJsonSerializer

Expression tree serializer/deserializer for Newtonsoft.Json.

Fork of aquilae/expression-json-serializer, created primarily to make the serializer thread-safe — upstream shares mutable dictionaries across threads, which is unusable under a concurrent consumer. Also adds multi-targeting. Published for use by DotNetWorkQueue.

Install

dotnet add package DotNetWorkQueue.Aq.ExpressionJsonSerializer

Supported targets

.NET 10.0
.NET 8.0
.NET Framework 4.8
.NET Standard 2.0

Usage

var settings = new JsonSerializerSettings();
settings.Converters.Add(new ExpressionJsonConverter(typeof(MyMessage)));

Expression<Func<MyMessage, bool>> expr = m => m.Value > 10;

string json = JsonConvert.SerializeObject(expr, settings);
var restored = JsonConvert.DeserializeObject<Expression<Func<MyMessage, bool>>>(json, settings);

Changes from upstream

Thread-safe: all internal dictionaries use ConcurrentDictionary. This is the main reason the fork exists — upstream's shared mutable caches corrupt under concurrent use.
Added net10.0, net8.0, net48, and netstandard2.0 multi-targeting
Merged partial loop and goto expression support (see limitation below)
Added NuGet packaging and GitHub Actions CI/publish pipeline

Known limitations

DebugInfoExpression and DynamicExpression are not implemented and throw NotImplementedException. DebugInfo needs a SymbolDocumentInfo and Dynamic needs a CallSiteBinder, neither of which is meaningfully serializable.

ListInit and MemberInit expressions do not round-trip on .NET Framework 4.8; they work on .NET 8 and .NET 10. Tracked in #8.

Everything else round-trips, including full statement-expression support: blocks, loops with break and continue, goto/label, switch, and try with catch, filter, fault and finally.

Build and CI

Pipeline	What it does
`.github/workflows/ci.yml`	Builds the solution and runs the test suite on net10.0 / net8.0 (ubuntu) and net48 (windows). Also packs and publishes to NuGet on a `v*` tag.
`.github/workflows/sonarcloud.yml`	SonarCloud CI-based analysis. Builds, runs the net10.0 tests with coverlet (OpenCover format), and feeds coverage to SonarCloud. Requires the `SONAR_TOKEN` repository secret. Rule exclusions are documented in `docs/sonar-exclusions.md`.
`Jenkinsfile`	Jenkins pipeline that fires on every PR (reported as the `continuous-integration/jenkins/pr-merge` check). Builds and runs the net10.0 / net8.0 test stages on a Docker agent.

To reproduce the Sonar coverage run locally:

dotnet build Aq.ExpressionJsonSerializer.sln -c Debug
dotnet test Aq.ExpressionJsonSerializer.Tests/Aq.ExpressionJsonSerializer.Tests.csproj \
  -f net10.0 -c Debug --no-build \
  --collect:"XPlat Code Coverage;Format=opencover"

Publishing a release

Publishing uses NuGet Trusted Publishing over GitHub OIDC — there is no long-lived API key. The publish job exchanges a short-lived OIDC token for a NuGet key valid for one hour, immediately before pushing.

Push a version tag: git tag v1.0.0 && git push origin v1.0.0
GitHub Actions runs build and tests across all targets, then packs and pushes to nuget.org automatically.

Trusted publishing setup

A one-time policy on nuget.org (your username → Trusted Publishing) backs this:

Field	Value
Policy owner	`blehnen`
Repository Owner	`blehnen`
Repository	`expression-json-serializer`
Workflow File	`ci.yml` (filename only, no path)
Environment	(blank — the publish job declares no GitHub environment)

To confirm the policy resolves without cutting a release, run the CI workflow manually from the Actions tab. That triggers the verify-trusted-publishing job, which performs the OIDC exchange and stops — it never pushes a package. Do this after any change to the policy or to the workflow filename, since the policy is bound to ci.yml by name.

1.1.0
- Implemented LabelExpression, SwitchExpression and TryExpression. Goto/label blocks now round-trip; previously only Expression.Loop with break/continue worked.
- Fixed serialization of unnamed parameters. Reduced nodes (compound assignment, increment/decrement) produce temporaries with no name, which were written as null and could not be read back.
- Fixed a race in label target creation: ContainsKey-then-index on a ConcurrentDictionary could return two different LabelTargets for one name.
- Throw TypeLoadException / MissingMethodException instead of bare System.Exception for unresolvable types and constructors.
- Test coverage raised from 62% to 87%.

Known limitation: ListInit and MemberInit expressions do not round-trip on .NET Framework 4.8. See https://github.com/blehnen/expression-json-serializer/issues/8
