Updated Marten from 8.37.1 to 9.2.0.

Release notes

Sourced from Marten's releases.

9.2.0

Marten 9.2.0

Features & changes

  • Override IEventStore.AllDatabases() on DocumentStore (#​4570, #​4571). Implements the store-agnostic database accessor added to JasperFx.Events.IEventStore. Delegates straight to ITenancy (mirroring IMartenStorage.AllDatabases()) and projects to IEventDatabase, so store-neutral monitoring/tooling can reach every database to call the read abstractions (AllProjectionProgress, FetchDeadLetterCountsAsync / CountDeadLetterEventsAsync) even when only IEventStore is registered in DI.

Dependencies

  • Upgraded all JasperFx.* packages to 2.2.0 (JasperFx, JasperFx.Events, JasperFx.Events.SourceGenerator, JasperFx.SourceGenerator).

Full Changelog: JasperFx/marten@V9.0.2...V9.2.0

9.0.2

Marten 9.0.2

A patch release that fixes #​4557 — self-aggregating projections failing for consumers that reference only the Marten package.

Fixes

  • #​4557 — Self-aggregating projections now work out of the box. Marten 9 dispatches conventional Apply/Create/ShouldDelete projection methods through the compile-time JasperFx.Events.SourceGenerator and has no runtime fallback, but the generator shipped as a DevelopmentDependency and never flowed to a consumer that only referenced the Marten package — surfacing as InvalidProjectionException: No source-generated dispatcher found ... at DocumentStore.For(...). Marten now bundles the analyzer in its own NuGet package, so a plain <PackageReference Include="Marten" /> runs the generator automatically. (#​4558)

  • Self-aggregating record aggregates work without a Snapshot<T> call site and without partial. Bumped JasperFx.Events / JasperFx.Events.SourceGenerator to 2.1.1 (JasperFx/jasperfx#​367): the generator now emits a self-aggregating evolver for a record from its own declaration (parity with classes), which also fixes the cross-assembly case where the aggregate type is defined in a different assembly than its registration.

  • Docs. Corrected the migration guide's projection section, which incorrectly stated Marten falls back to a runtime evolver lookup for non-partial convention projections; documented that self-aggregating Snapshot<T> types do not need to be partial (only projection subclasses do).

Dependency bumps

  • JasperFx.Events 2.1.0 → 2.1.1
  • JasperFx.Events.SourceGenerator 2.1.0 → 2.1.1

No public API changes from 9.0.1.

9.0.1

Marten 9.0.1

A patch release on the Critter Stack 2026 foundation, rolling up the latest JasperFx 2.0.1 / JasperFx.Events 2.1.0 / Weasel 9.0.1 dependencies along with several source-generator and reliability fixes.

Foundation bumps

  • JasperFx 2.0.0 → 2.0.1
  • JasperFx.Events / JasperFx.Events.SourceGenerator → 2.1.0
  • JasperFx.SourceGeneration → JasperFx.SourceGenerator 2.0.1 (package renamed; #​4555)
  • Weasel.Postgresql / Weasel.EntityFrameworkCore 9.0.0 → 9.0.1

Fixes

  • Self-aggregating source-generator fixes (via JasperFx.Events 2.1.0, consumed in #​4547):
    • #​4542 — required members on self-aggregating snapshot types no longer break generated evolver construction; default! is emitted only when a public parameterless constructor exists, otherwise RuntimeHelpers.GetUninitializedObject is used.
    • #​4543 — nullable [ReadAggregate] aggregate parameters generate correctly.
  • #​4546 — IEventDatabase dead-letter count reads (CountDeadLetterEventsAsync / FetchDeadLetterCountsAsync) are implemented on MartenDatabase via LINQ over the DeadLetterEvent document.
  • #​4540 — opt-in System.Text.Json source-generation context support (SystemTextJsonSerializer.UseTypeInfoResolver) for AOT/trimming-friendly metadata.
  • #​4552 — intermittent CI flakes fixed: feature_flag_positive advisory-lock contention (distinct ApplyChangesLockId, #​4553) and the conjoined multi-tenant query_before_saving XX000: tuple concurrently updated migration-DDL race (resolved upstream in Weasel 9.0.1 / weasel#​293).

No public API breaking changes from 9.0.0. RestoreV8Defaults() continues to revert the 9.0 default flips.

9.0.0

Marten 9.0.0 — Critter Stack 2026

The headline release of the Critter Stack 2026 wave, on the final JasperFx 2.0 + Weasel 9.0 foundation.

Highlights

  • Foundation: JasperFx 2.0.0 / JasperFx.Events 2.0.0 / Weasel 9.0.0 (final). Targets net9.0;net10.0.
  • No runtime code generation. Roslyn is gone — JasperFx.RuntimeCompiler is no longer a dependency. Document/event storage is hand-written closed-shape; compiled queries use Marten.SourceGenerator. No codegen write step for Marten.
  • Cold-start + AOT: AOT-publishable in Static mode; lazy document-mapping materialization; per-query handler-factory caching.
  • Dedupe pillar (jasperfx#​214): IStorageOperation rebased on Weasel.Core; async-daemon distributor concretes consumed from JasperFx.Events.Daemon; OperationRole / BulkInsertMode relocated to Weasel.Core.
  • Defaults flipped to best-perf: QuickWithServerTimestamps append mode, advanced async tracking, bigint events, lightweight default sessions, System.Text.Json default — all revertable via RestoreV8Defaults().
  • Versioning: IRevisioned.Version stays int (V8-compatible); new ILongVersioned (long) for MultiStreamProjection documents.
  • DCB: optional HSTORE tag storage; FetchForWritingByTags<T> for identity-less boundary aggregates.

See the migration guide (docs/migration-guide.md). Master plan: marten#​4349. Ships in lockstep with Polecat 4.0.

🐛 Bug Fixes / Codegen

#​2963 (closes #​2958): EF Core transaction middleware + post-save cascade flush

The HTTP-handler codegen path under the EF Core transaction middleware + outbox cascade (GH-536) no longer fails handler compilation. Two related codegen issues addressed in this PR:

  • CS0128 duplicate var messageContext declaration in the generated handler. Cherry-picked from #​2959, originally authored by @​kentcooper — credit preserved on commit 9df45bfde. Root cause: MessageBusSource was returning a fresh CreateMessageContextWithMaybeTenantFrame per call; once cached + always returning the concrete MessageContext, the duplicate goes away.
  • CS1061 'IMessageContext' does not contain a definition for EnqueueCascadingAsync — surfaced after the cache fix because once the source produced a concrete MessageContext Variable, the downstream CaptureCascadingMessages frame still declared its MethodCall target as typeof(IMessageContext) and emitted a bad ((IMessageContext)messageContext).EnqueueCascadingAsync(…) cast. Fixed by re-targeting CaptureCascadingMessages to the concrete MessageContext type — mirrors the existing FlushOutgoingMessages pattern. Latent in src/Wolverine/Runtime/Handlers/CaptureCascadingMessages.cs since 020e79013e (2022-09-16); the variable-cache fix is what flipped it from masked to visible.

📦 Dependency bumps

  • JasperFx + JasperFx.Events + JasperFx.Events.SourceGenerator + JasperFx.SourceGenerator 2.2.1 → 2.2.3
  • JasperFx.RuntimeCompiler unchanged (own 5.x line, stays at 5.0.0)
  • Marten / Polecat unchanged (9.2.0 / 4.2.1)

Upstream JasperFx 2.2.2 release: https://github.com/JasperFx/jasperfx/releases/tag/V2.2.2 (Fix source-created codegen variable reuse, #​392). 2.2.3 was a same-day version-bump-only re-roll.

📖 Documentation

  • #​2960 (@​outofrange-consulting): clarify the JasperFx command-line integration link in the diagnostics docs.
  • #​2964 (closes #​2962): re-align the dead-letter REST API reference with the current DeadLetterEnvelopeGetRequest / DeadLetterEnvelopeResults / DeadLetterEnvelopeIdsRequest signatures — the docs still described the pre-5 cursor-based pagination (StartId/NextId) and the legacy DeadLetterEnvelopesFoundResponse wrapper. Updated for offset-based PageNumber pagination, the multi-store IReadOnlyList<DeadLetterEnvelopeResults> response shape, and tenant-aware Ids request bodies.

🧪 Known issues

  • #​2965: SharedMemory transport does not serialize envelopes on cross-host send. Surfaces as a MartenTests.Distribution.with_ancillary_stores.spread_out_over_multiple_hosts failure where AssignAgent system commands arrive at the destination node with empty Data/MessageType and the receive pipeline can't deserialize them. Long-standing — the marten CI workflow has been red on this test through V6.2.0 and V6.2.1, predates this release line entirely. Unblocked the V6.2.2 cycle by adding [Fact(Skip = "…")] referencing #​2965; the underlying serialization bug is tracked separately and is out of scope for a JasperFx pin-bump patch release.

6.2.0

Bug-fix + feature release on top of 6.1.0 — 13 PRs.

✨ New features

Custom Result<T> Support — #​2952 (refs #​2221)

First three phases of native Result<T>-style handler return-value support: ResultPolicy registry, handler-side unwrapping seams, and caller-side InvokeAsync<T> unwrap. Lays the groundwork for integrating with libraries like ErrorOr, OneOf, FluentResults, etc.

DbContext Abstractions for EF Core Transaction Middleware — #​2919, #​2954

The EF Core transaction middleware now binds correctly when handler parameters are declared as interface or abstract base abstractions over a concrete DbContext. Multiple abstractions to the same DbContext are supported in a single handler — the runtime resolves them all to the same scoped instance, and the transaction still auto-applies.

📖 DbContext Abstractions docs

🚀 Performance

Outgoing Envelope Pooling — #​2956 (closes #​2955)

MessageRouter.RouteForPublish now acquires from the runtime envelope pool (originally introduced in #​2741 for the Executor sites in 6.1.0) when the route's sender is an InlineSendingAgent or BufferedSendingAgent. Measured −504 B/op (−90 %) on the transport-bound publish/send paths in the CritterStackScalability harness, with ~10× fewer Gen0 collections per 1k ops. DurableSendingAgent, local-queue agents, and ISenderRequiresCallback senders are explicitly excluded — different lifecycle plumbing required, tracked as follow-ups.

🐛 Bug fixes

Marten / Polecat

  • #​2943 Fix scheduled-cascade loss from [ReadAggregate] / [DocumentExists] handlers (closes #​2941).
  • #​2948 Pre-populate chain.AncillaryStoreType in Phase A so the inbox-routing map sees [MartenStore] (closes #​2944).
  • #​2947 Bump Polecat 4.1.1 → 4.2.1 and unskip the three Polecat scheduled-cascade tests.

Persistence (Postgres / MySQL)

  • #​2945 Route PostgresqlQueue identifiers through Weasel's PostgresqlIdentifier.Shorten() so long queue names don't overflow Postgres's 63-byte identifier limit (closes #​2942).
  • #​2946 Emit PersistNodeRecord SQL with unquoted schema (MySQL, closes #​2940).

6.1.0

Wolverine 6.1.0

Minor release. Critter Stack dependency refresh, plus the rollup of the entire post-6.0.0 6.0.x line — most significantly the AOT runtime-scanning-elimination work and a new command-line handler-discovery diagnostic.

ℹ️ There was no standalone 6.0.1 tag/GitHub release (it shipped as a NuGet version only), so the changelog below covers every PR merged since 6.0.0 — which includes everything released as 6.0.1 through 6.0.3.

Dependencies

  • Marten / Marten.AspNetCore / Marten.Newtonsoft: 9.0.1 → 9.2.0
  • JasperFx.* (non-RuntimeCompiler): 2.1.3 → 2.2.0 (#​2938)
  • Polecat: 4.1.1 (unchanged — already latest)
  • JasperFx.RuntimeCompiler: 5.0.0 (unchanged — own 5.x line)

Marten 9.2.0 now bundles JasperFx.Events.SourceGenerator as an analyzer, so projects referencing Wolverine.Marten receive it transitively. The previously-explicit analyzer references were dropped from the 8 Marten-referencing projects to avoid running the generator twice, which produced duplicate Evolve/*Evolver build errors (#​2939). PolecatTests retains its explicit reference because Polecat does not bundle the generator.

New & Noteworthy

AOT: eliminate runtime assembly scanning — AOT Publishing. Static-mode apps no longer scan assemblies at startup; discovery now flows through source-generated manifests:

  • Handlers + message types — #​2906 / #​2928
  • HTTP endpoints — #​2925 / #​2929
  • gRPC services (incl. the direct-mapped mode) — #​2926 / #​2930 / #​2934
  • [WolverineHandlerModule] assemblies, with no filesystem probe — #​2905 / #​2935
  • Extension discovery manifest — #​2902 / #​2918
  • Remaining ad-hoc discovery scans routed through JasperFx TypeQuery — #​2909 / #​2932
  • Generated HTTP/gRPC types attached by full name instead of a GetTypes() scan — #​2908 / #​2936

Command-line handler-discovery diagnostic — Command Line Integration · Command Line Diagnostics tutorial. New dotnet run -- wolverine-diagnostics describe-handlers <Type> runs DescribeHandlerMatch from the CLI so you can troubleshoot handler discovery without editing your bootstrapping code — #​2921 / #​2923

Build-time OpenAPI generation — Command Line Integration. dotnet run -- openapi generates the OpenAPI document without starting the host (no database/broker required) — #​2903 / #​2911

SQS fair queues on standard queues — support MessageGroupId on standard Amazon SQS queues — #​2886 / #​2889

SignalR ClaimsPrincipal — the connection's ClaimsPrincipal is now exposed on SignalREnvelope — #​2927 / #​2937

EF Core transactional outbox timing fix — the EF Core transaction and outbox flush now complete before the HTTP response is written — #​2917 / #​2920

Mixed-lifetime IEnumerable<T> support; Lamar removed — handlers depending on a mixed singleton/scoped IEnumerable<T> now resolve every element correctly; Lamar is no longer used or supported, and the built-in ServiceProvider is the container — #​2896 / #​2914

Aggregate handler naming clarity — clarified and guarded the *AggregateHandler naming convention vs. [ReadAggregate] — #​2924

Production code-generation guidance — Code Generation. How to drop Roslyn from production images, with a linked CqrsMinimalApi sample — #​2900 / #​2912

Bug fixes

  • Ancillary store outbox schema for projection side effects — #​2887 / #​2888
  • NRE from null-Sender routes built during description mode — #​2897 / #​2899

6.0.0

Wolverine 6.0.0 — Critter Stack 2026

The messaging/orchestration release completing the Critter Stack 2026 wave, on the final foundation (JasperFx 2.0 / Weasel 9.0 / Marten 9.0 / Polecat 4.0).

Highlights

  • Foundation (final): JasperFx 2.0.0 / JasperFx.RuntimeCompiler 5.0.0 / Marten 9.0.0 / Polecat 4.0.0 / Weasel 9.0.0. Targets net9.0;net10.0.
  • Runtime codegen decoupled from core (BREAKING): WolverineFx no longer ships Roslyn. Apps in the default TypeLoadMode.Dynamic must add WolverineFx.RuntimeCompilation, or pre-generate via codegen write + TypeLoadMode.Static (the trimmer then drops Roslyn). See the migration guide.
  • ServiceLocationPolicy.NotAllowed is the default (BREAKING) — restructure registrations, allow-list per type, or call opts.RestoreV5Defaults() to revert.
  • AOT-clean (pillar #​213): every packaged library carries IsAotCompatible=true (except the intentional WolverineFx.RuntimeCompilation); Static-mode publish drops Roslyn.
  • Cold-start (pillar #​212): Tier-1 pre-generated static handler registry skips handler-discovery scanning in Static mode.
  • Newtonsoft extracted to WolverineFx.Newtonsoft / WolverineFx.Http.Newtonsoft; IForwardsTo<T> discovery now explicit; removed [Obsolete] APIs (EventForwardingToWolverine, RedisTransport.BuildRedisStreamUri, PulsarEndpoint.UriFor).

Migration guide: https://wolverinefx.net/guide/migration.html (or docs/guide/migration.md). Master plan: wolverine#​2715. Remaining release-cut comms items tracked in #​2745.

Wolverine 6.0.0 — Critter Stack 2026

The messaging/orchestration release completing the Critter Stack 2026 wave, on the final foundation (JasperFx 2.0 / Weasel 9.0 / Marten 9.0 / Polecat 4.0).

Highlights

  • Foundation (final): JasperFx 2.0.0 / JasperFx.RuntimeCompiler 5.0.0 / Marten 9.0.0 / Polecat 4.0.0 / Weasel 9.0.0. Targets net9.0;net10.0.
  • Runtime codegen decoupled from core (BREAKING): WolverineFx no longer ships Roslyn. Apps in the default TypeLoadMode.Dynamic must add WolverineFx.RuntimeCompilation, or pre-generate via codegen write + TypeLoadMode.Static (the trimmer then drops Roslyn). See the migration guide.
  • ServiceLocationPolicy.NotAllowed is the default (BREAKING) — restructure registrations, allow-list per type, or call opts.RestoreV5Defaults() to revert.
  • AOT-clean (pillar #​213): every packaged library carries IsAotCompatible=true (except the intentional WolverineFx.RuntimeCompilation); Static-mode publish drops Roslyn.
  • Cold-start (pillar #​212): Tier-1 pre-generated static handler registry skips handler-discovery scanning in Static mode.
  • Newtonsoft extracted to WolverineFx.Newtonsoft / WolverineFx.Http.Newtonsoft; IForwardsTo<T> discovery now explicit; removed [Obsolete] APIs (EventForwardingToWolverine, RedisTransport.BuildRedisStreamUri, PulsarEndpoint.UriFor).

Migration guide: https://wolverinefx.net/guide/migration.html (or docs/guide/migration.md). Master plan: wolverine#​2715. Remaining release-cut comms items tracked in #​2745.

🐛 Bug Fixes / Codegen

#​2963 (closes #​2958): EF Core transaction middleware + post-save cascade flush

The HTTP-handler codegen path under the EF Core transaction middleware + outbox cascade (GH-536) no longer fails handler compilation. Two related codegen issues addressed in this PR:

  • CS0128 duplicate var messageContext declaration in the generated handler. Cherry-picked from #​2959, originally authored by @​kentcooper — credit preserved on commit 9df45bfde. Root cause: MessageBusSource was returning a fresh CreateMessageContextWithMaybeTenantFrame per call; once cached + always returning the concrete MessageContext, the duplicate goes away.
  • CS1061 'IMessageContext' does not contain a definition for EnqueueCascadingAsync — surfaced after the cache fix because once the source produced a concrete MessageContext Variable, the downstream CaptureCascadingMessages frame still declared its MethodCall target as typeof(IMessageContext) and emitted a bad ((IMessageContext)messageContext).EnqueueCascadingAsync(…) cast. Fixed by re-targeting CaptureCascadingMessages to the concrete MessageContext type — mirrors the existing FlushOutgoingMessages pattern. Latent in src/Wolverine/Runtime/Handlers/CaptureCascadingMessages.cs since 020e79013e (2022-09-16); the variable-cache fix is what flipped it from masked to visible.

📦 Dependency bumps

  • JasperFx + JasperFx.Events + JasperFx.Events.SourceGenerator + JasperFx.SourceGenerator 2.2.1 → 2.2.3
  • JasperFx.RuntimeCompiler unchanged (own 5.x line, stays at 5.0.0)
  • Marten / Polecat unchanged (9.2.0 / 4.2.1)

Upstream JasperFx 2.2.2 release: https://github.com/JasperFx/jasperfx/releases/tag/V2.2.2 (Fix source-created codegen variable reuse, #​392). 2.2.3 was a same-day version-bump-only re-roll.

📖 Documentation

  • #​2960 (@​outofrange-consulting): clarify the JasperFx command-line integration link in the diagnostics docs.
  • #​2964 (closes #​2962): re-align the dead-letter REST API reference with the current DeadLetterEnvelopeGetRequest / DeadLetterEnvelopeResults / DeadLetterEnvelopeIdsRequest signatures — the docs still described the pre-5 cursor-based pagination (StartId/NextId) and the legacy DeadLetterEnvelopesFoundResponse wrapper. Updated for offset-based PageNumber pagination, the multi-store IReadOnlyList<DeadLetterEnvelopeResults> response shape, and tenant-aware Ids request bodies.

🧪 Known issues

  • #​2965: SharedMemory transport does not serialize envelopes on cross-host send. Surfaces as a MartenTests.Distribution.with_ancillary_stores.spread_out_over_multiple_hosts failure where AssignAgent system commands arrive at the destination node with empty Data/MessageType and the receive pipeline can't deserialize them. Long-standing — the marten CI workflow has been red on this test through V6.2.0 and V6.2.1, predates this release line entirely. Unblocked the V6.2.2 cycle by adding [Fact(Skip = "…")] referencing #​2965; the underlying serialization bug is tracked separately and is out of scope for a JasperFx pin-bump patch release.

6.2.0

Bug-fix + feature release on top of 6.1.0 — 13 PRs.

✨ New features

Custom Result<T> Support — #​2952 (refs #​2221)

First three phases of native Result<T>-style handler return-value support: ResultPolicy registry, handler-side unwrapping seams, and caller-side InvokeAsync<T> unwrap. Lays the groundwork for integrating with libraries like ErrorOr, OneOf, FluentResults, etc.

DbContext Abstractions for EF Core Transaction Middleware — #​2919, #​2954

The EF Core transaction middleware now binds correctly when handler parameters are declared as interface or abstract base abstractions over a concrete DbContext. Multiple abstractions to the same DbContext are supported in a single handler — the runtime resolves them all to the same scoped instance, and the transaction still auto-applies.

📖 DbContext Abstractions docs

🚀 Performance

Outgoing Envelope Pooling — #​2956 (closes #​2955)

MessageRouter.RouteForPublish now acquires from the runtime envelope pool (originally introduced in #​2741 for the Executor sites in 6.1.0) when the route's sender is an InlineSendingAgent or BufferedSendingAgent. Measured −504 B/op (−90 %) on the transport-bound publish/send paths in the CritterStackScalability harness, with ~10× fewer Gen0 collections per 1k ops. DurableSendingAgent, local-queue agents, and ISenderRequiresCallback senders are explicitly excluded — different lifecycle plumbing required, tracked as follow-ups.

🐛 Bug fixes

Marten / Polecat

  • #​2943 Fix scheduled-cascade loss from [ReadAggregate] / [DocumentExists] handlers (closes #​2941).
  • #​2948 Pre-populate chain.AncillaryStoreType in Phase A so the inbox-routing map sees [MartenStore] (closes #​2944).
  • #​2947 Bump Polecat 4.1.1 → 4.2.1 and unskip the three Polecat scheduled-cascade tests.

Persistence (Postgres / MySQL)

  • #​2945 Route PostgresqlQueue identifiers through Weasel's PostgresqlIdentifier.Shorten() so long queue names don't overflow Postgres's 63-byte identifier limit (closes #​2942).
  • #​2946 Emit PersistNodeRecord SQL with unquoted schema (MySQL, closes #​2940).

Pulsar

  • #​2950 Fix KeyNotFoundException acking batch messages on partitioned topics (supersedes #​2883).

Distributed agents

  • #​2951 Bump remote-node agent InvokeAsync<T> reply timeout 10 s → 30 s (closes #​2949).

Quality

  • #​2894 Dispose more resources (@​dmytro-pryvedeniuk).

📖 Documentation

  • #​2953 AOT callout for FluentValidation in the HTTP validation guide (addresses #​2910). 📖 HTTP validation docs
  • #​2954 Extended docs + scenario tests for the new EF Core DbContext abstractions (above).

📦 Dependency bumps

  • Polecat 4.1.1 → 4.2.1 (#​2947).

6.1.0

Wolverine 6.1.0

Minor release. Critter Stack dependency refresh, plus the rollup of the entire post-6.0.0 6.0.x line — most significantly the AOT runtime-scanning-elimination work and a new command-line handler-discovery diagnostic.

ℹ️ There was no standalone 6.0.1 tag/GitHub release (it shipped as a NuGet version only), so the changelog below covers every PR merged since 6.0.0 — which includes everything released as 6.0.1 through 6.0.3.

Dependencies

  • Marten / Marten.AspNetCore / Marten.Newtonsoft: 9.0.1 → 9.2.0
  • JasperFx.* (non-RuntimeCompiler): 2.1.3 → 2.2.0 (#​2938)
  • Polecat: 4.1.1 (unchanged — already latest)
  • JasperFx.RuntimeCompiler: 5.0.0 (unchanged — own 5.x line)

Marten 9.2.0 now bundles JasperFx.Events.SourceGenerator as an analyzer, so projects referencing Wolverine.Marten receive it transitively. The previously-explicit analyzer references were dropped from the 8 Marten-referencing projects to avoid running the generator twice, which produced duplicate Evolve/*Evolver build errors (#​2939). PolecatTests retains its explicit reference because Polecat does not bundle the generator.

New & Noteworthy

AOT: eliminate runtime assembly scanning — AOT Publishing. Static-mode apps no longer scan assemblies at startup; discovery now flows through source-generated manifests:

  • Handlers + message types — #​2906 / #​2928
  • HTTP endpoints — #​2925 / #​2929
  • gRPC services (incl. the direct-mapped mode) — #​2926 / #​2930 / #​2934
  • [WolverineHandlerModule] assemblies, with no filesystem probe — #​2905 / #​2935
  • Extension discovery manifest — #​2902 / #​2918
  • Remaining ad-hoc discovery scans routed through JasperFx TypeQuery — #​2909 / #​2932
  • Generated HTTP/gRPC types attached by full name instead of a GetTypes() scan — #​2908 / #​2936

Command-line handler-discovery diagnostic — Command Line Integration · Command Line Diagnostics tutorial. New dotnet run -- wolverine-diagnostics describe-handlers <Type> runs DescribeHandlerMatch from the CLI so you can troubleshoot handler discovery without editing your bootstrapping code — #​2921 / #​2923

Build-time OpenAPI generation — Command Line Integration. dotnet run -- openapi generates the OpenAPI document without starting the host (no database/broker required) — #​2903 / #​2911

SQS fair queues on standard queues — support MessageGroupId on standard Amazon SQS queues — #​2886 / #​2889

SignalR ClaimsPrincipal — the connection's ClaimsPrincipal is now exposed on SignalREnvelope — #​2927 / #​2937

EF Core transactional outbox timing fix — the EF Core transaction and outbox flush now complete before the HTTP response is written — #​2917 / #​2920

Looks like these dependencies are updatable in another way, so this is no longer needed.
