Context

Stage 2 of implementing IBuildEngine callback support in TaskHost. Stage 1 (#13149) established the packet infrastructure and implemented IsRunningMultipleNodes. This PR adds RequestCores/ReleaseCores (IBuildEngine9) using the same pattern.

Previously, tasks running in TaskHost that called RequestCores or ReleaseCores would get a NotImplementedException. This blocked resource-aware tasks from properly coordinating CPU usage when running out-of-process.

Partial fix for #12863

Changes Made

New Packets:

  • TaskHostCoresRequest (0x22) — single packet type for both operations, with IsRelease bool to distinguish RequestCores vs ReleaseCores
  • TaskHostCoresResponse (0x23) — returns GrantedCores (int) for RequestCores, 0 for ReleaseCores acknowledgment

OutOfProcTaskHostNode (TaskHost side):

  • Replace throw NotImplementedException() with SendCallbackRequestAndWaitForResponse<TaskHostCoresResponse>()
  • Add input validation (requestedCores > 0, coresToRelease > 0) matching in-process behavior
  • Gate behind CallbacksSupported — when disabled, RequestCores returns 0, ReleaseCores is no-op (both log MSB5022)
  • Register TaskHostCoresResponse in packet handler and route in HandlePacket switch

TaskHostTask (Worker node side):

  • Register TaskHostCoresRequest packet handler
  • HandleCoresRequest(): forwards RequestCores/ReleaseCores to the in-process IBuildEngine9
  • The real implicit-core/additional-core accounting happens in the in-process TaskHost class — the OOP node is a thin proxy

Callback Flow

Testing

  • Packet serialization (4 tests): Round-trip for request (RequestCores/ReleaseCores variants) and response (granted/acknowledgment)
  • Integration (5 tests):
    • RequestCores_WorksWithExplicitTaskHostFactory — verifies cores granted >= 1
    • RequestAndReleaseCores_WorksWithExplicitTaskHostFactory — full request+release cycle
    • RequestCores_WorksWhenAutoEjectedInMultiThreadedMode — MT auto-ejection to TaskHost
    • RequestCores_LogsErrorWhenCallbacksNotSupported — MSB5022 fallback
    • IsRunningMultipleNodes_LogsErrorWhenCallbacksNotSupported — Stage 1 fallback (unchanged)
  • E2E cross-runtime (1 test): NetTaskHost_CallbackRequestCoresTest via bootstrapped MSBuild
  • All 20 callback/serialization/lifecycle tests pass, 0 regressions

Documentation

Updated taskhost-threading.md with:

  • Supported callbacks table (IsRunningMultipleNodes, RequestCores, ReleaseCores)
  • Resource management flow description

Next Stages

  • Stage 3: BuildProjectFile/BuildProjectFilesInParallel
  • Stage 4: Yield/Reacquire

JanProvaznik and others added 5 commits February 27, 2026 16:57
New IPC packet pair for forwarding IBuildEngine9.RequestCores() and
ReleaseCores() from TaskHost to the owning worker node.

TaskHostCoresRequest (0x22) uses a single packet type with an IsRelease
bool to distinguish RequestCores from ReleaseCores — both operations
share the same int parameter semantics (core count) and response shape
(granted cores or acknowledgment).

TaskHostCoresResponse (0x23) returns GrantedCores for RequestCores calls
and 0 as acknowledgment for ReleaseCores calls.

Both implement ITaskHostCallbackPacket for request/response correlation
via RequestId, following the Stage 1 pattern (TaskHostIsRunningMultipleNodes*).

The NodePacketType enum values 0x22/0x23 were already reserved; this
commit updates their doc comments to use 'owning worker node' terminology.

Replace 'throw NotImplementedException()' stubs with callback-based
forwarding using the Stage 1 SendCallbackRequestAndWaitForResponse<T>
infrastructure.

Both methods:
- Validate input (requestedCores/coresToRelease > 0) before IPC roundtrip,
  matching the in-process TaskHost's fail-fast behavior
- Check CallbacksSupported gate — when disabled, RequestCores returns 0
  and ReleaseCores is no-op, both logging MSB5022
- Send TaskHostCoresRequest and block on TaskHostCoresResponse via TCS

Register TaskHostCoresResponse handler in the constructor and add the
response routing case to HandlePacket's switch statement.

Register TaskHostCoresRequest handler and add HandleCoresRequest() which
forwards calls to the in-process TaskHost's IBuildEngine9 implementation.

The OOP TaskHostNode is a thin proxy — the real implicit-core accounting
and scheduler communication happens in the in-process TaskHost class on
the worker node side. HandleCoresRequest dispatches based on IsRelease:
- RequestCores: forwards to engine9.RequestCores(), returns GrantedCores
- ReleaseCores: forwards to engine9.ReleaseCores(), returns 0 (ack)

When _buildEngine doesn't implement IBuildEngine9 (shouldn't happen in
practice), RequestCores returns 0 and ReleaseCores is no-op — matching
the HandleIsRunningMultipleNodesRequest pattern for IBuildEngine2.

RequestCoresTask is a test task that calls IBuildEngine9.RequestCores(N)
and optionally ReleaseCores. It exposes GrantedCores as an output property
for assertion. Linked into ExampleTask.csproj for E2E cross-runtime use.

TestNetTaskResourceCallback/ is the E2E test project that runs
RequestCoresTask via TaskHostFactory with Runtime='NET', mirroring
the TestNetTaskCallback/ project from Stage 1.

Packet serialization (4 tests):
- TaskHostCoresRequest round-trip for RequestCores and ReleaseCores
- TaskHostCoresResponse round-trip for granted cores and acknowledgment

Integration (5 tests):
- RequestCores via explicit TaskHostFactory — verifies granted >= 1
- RequestCores + ReleaseCores full cycle — verifies no errors
- RequestCores auto-ejected in MT mode — verifies TaskHost forwarding
- RequestCores fallback when callbacks disabled — verifies MSB5022
- IsRunningMultipleNodes fallback (Stage 1, unchanged)

E2E cross-runtime (1 test):
- NetTaskHost_CallbackRequestCoresTest via bootstrapped MSBuild

NotImplementedException:

- EmccCompile: caused blazorwasm publish failure (dotnet/sdk#53300)
- MonoAOTCompiler, ILStrip, EmitBundleBase: same latent bug

The failure chain was:
1. RequestCores returns 0 (no exception thrown)
2. allowedParallelism becomes 0
3. Parallel.ForEach with MaxDegreeOfParallelism=0 throws
4. ReleaseCores(0) in finally block throws ArgumentOutOfRangeException

Fix: track cores actually acquired separately. If RequestCores returns 0
or throws any exception, fall back to the original parallelism and skip
ReleaseCores.

…ker node (#13350)

## Summary

Stage 3 of IBuildEngine callback support for out-of-process TaskHost.
Implements forwarding of `BuildProjectFile*` from OOP TaskHost to the
owning worker node, enabling tasks ejected to TaskHost (via `-mt` or
explicit `TaskHostFactory`) to build other projects.

**Real-world impact:** WPF XAML compilation uses
`GenerateTemporaryTargetAssembly` which calls `BuildProjectFile` from
TaskHost. Without this change, building any WPF project with `-mt` fails
with MSB5022.

## Design

### Packet pair
- `TaskHostBuildRequest` (0x20) / `TaskHostBuildResponse` (0x21): All 4
`BuildProjectFile*` overloads normalize to the 6-param
`BuildProjectFilesInParallel` canonical form.

### Callback flow (no Yield/Reacquire)

Unlike the original design, we do **not** use `Yield`/`Reacquire` for
`BuildProjectFile` callbacks. Instead:

1. Task thread calls `BuildProjectFile` → gates on `CallbacksSupported`
2. `BlockForCallback()` transitions the task from _active_ to _blocked_
(`_activeTaskCount--`, `_blockedTaskCount++`)
3. `SendCallbackRequestAndWaitForResponse<T>` serializes the request and
blocks on `TaskCompletionSource`
4. Worker's `TaskHostTask.HandleBuildRequest` calls
`IBuildEngine3.BuildProjectFilesInParallel` — exceptions propagate to
`TaskBuilder` naturally (matching in-proc behavior), `finally` sends the
response
5. Response arrives → TCS completes → `ResumeAfterCallback()` restores
counters and environment

A blocked task does _not_ prevent the node from accepting new work —
`HandleTaskHostConfiguration` checks `_activeTaskCount == 0` (not
blocked count), so nested task dispatch works.

`Yield`/`Reacquire` remain  no-ops in the OOP TaskHost.
### Per-task isolation
`TaskExecutionContext` stores per-task state via
`ConcurrentDictionary<int, TaskExecutionContext>` + `AsyncLocal`:
configuration, task wrapper, saved environment, debug flags, warning
settings, pending callback requests. `GetCurrentConfiguration()` and
`EffectiveWarningsAs*` read from per-task context on task threads,
falling back to `_currentConfiguration` on the main communication
thread.

### Handler routing (process reuse)
`NodeProviderOutOfProcTaskHost` routes packets by `TaskHostNodeKey`,
supporting nested task dispatch when an outer task is blocked on a
callback and a new task arrives on the same TaskHost process.

### Version gating
Gated behind `CallbacksSupported` (`_parentPacketVersion >= 4` OR
`MSBUILDENABLETASKHOSTCALLBACKS=1`). Each `BuildProjectFile` overload
explicitly checks. Follow-up PR bumps `PacketVersion` to 4 and removes
the env var.

## Tests
- **Serialization tests** — packet round-trip for
`TaskHostBuildRequest`/`Response` with null/empty/populated properties
- **Integration tests** — `BuildProjectFile` via `TaskHostFactory`,
global property forwarding, target output retrieval,
callbacks-not-supported error path (MSB5022)
- **E2E tests** — cross-runtime `BuildProjectFile` callback, TaskHost
process reuse (same PID verification)
- **MT mode test** — `BuildProjectFile` during `-mt` build

## Context
- Spec: #12868
- Stage 1: #13149 (merged) — `IsRunningMultipleNodes`
- Stage 2: #13306 (merged) — `RequestCores`/`ReleaseCores`
- WPF repro: #12863
