* Adding support for events & shared state in durable workflows.
* PR feedback fixes
* PR feedback fixes.
* Add YieldOutputAsync calls to 05_WorkflowEvents sample executors
The integration test asserts that WorkflowOutputEvent is found in the
stream, but the sample executors only used AddEventAsync for custom
events and never called YieldOutputAsync. Since WorkflowOutputEvent is
only emitted via explicit YieldOutputAsync calls, the assertion would
fail. Added YieldOutputAsync to each executor to match the test
expectation and demonstrate the API in the sample.

* .NET: [Feature Branch] Add Human In the Loop support for durable workflows (#4358)
* Add Azure Functions HITL workflow sample
Add 06_WorkflowHITL Azure Functions sample demonstrating Human-in-the-Loop
workflow support with HTTP endpoints for status checking and approval responses.
The sample includes:
- ExpenseReimbursement workflow with RequestPort for manager approval
- Custom HTTP endpoint to check workflow status and pending approvals
- Custom HTTP endpoint to send approval responses via RaiseEventAsync
- demo.http file with step-by-step interaction examples
* PR feedback fixes
* Minor comment cleanup
* Minor comment clReverted the `!context.IsReplaying` guards on `PendingEvents.Add`/`RemoveAll` and `SetCustomStatus` in `ExecuteRequestPortAsync`. The guards broke fan-out scenarios where parallel RequestPorts need to be discoverable after replay. `SetCustomStatus` is idempotent metadata that doesn't affect replay determinism.eanup

* Improvements to README
* Update samples to use parallel request ports.
* Unit tests
* Introduce local variables to improve readability of Workflows.Workflows access patter
* Use GitHub-style callouts and add PowerShell command variants in HITL sample README

* Fix GetExecutorName to handle agent names with underscores
Split on last underscore instead of first, and validate that the
suffix is a 32-char hex string (sanitized GUID) before stripping it.
This prevents truncation of agent names like 'my_agent' when the
executor ID is 'my_agent_<guid>'.

- DurableTask.Client.AzureManaged: 1.19.1 -> 1.22.0
- DurableTask.Worker: 1.19.1 -> 1.22.0
- DurableTask.Worker.AzureManaged: 1.19.1 -> 1.22.0
- Azure Functions extensions kept at original versions (1.13.1/1.0.1) due to
host-side DurableTask.Core 3.7.0 incompatibility with newer extensions

* Update Microsoft.Azure.Functions.Worker.Extensions.DurableTask to "1.16.0"
* Add the local.settings.json files to the sample which were previously ignored. This aligns with our other samples.
* Increase timeout for tests as CI has them failing transiently.
* increaset timeout value for azure functions integration tests.
* Add YieldsOutput(string) to workflow shared state sample executors
ValidateOrder and EnrichOrder call YieldOutputAsync with string messages,
but only their TOutput (OrderDetails) was in the allowed yield types.
This caused TargetInvocationException in the WorkflowSharedState sample
validation integration test.
* Downgrade the durable packages to 1.18.0
* Downgrading Worker.Extensions.DurableTask to 1.12.1

* Filter empty AIContent from durable agent state responses
Prevent opaque AIContent objects (e.g., with only RawRepresentation set)
from being stored in durable entity state, where they serialize to empty
JSON payloads. Base AIContent instances are kept only if they have
Annotations or AdditionalProperties.
