Pull request overview
Ports the Python Magentic multi-agent orchestration sample to .NET, adding a new console sample under samples/03-workflows/Orchestration/Magentic/ that uses MagenticWorkflowBuilder with a researcher agent, a coder agent (with HostedCodeInterpreterTool), and an LLM-backed manager. It streams orchestration events (initial plan, replans, progress-ledger updates) and prints the final transcript. The PR description also mentions an Evaluation API cleanup (removing EvalItem.ExpectedOutput / Evaluation_WorkflowExpectedOutputs), but those changes are not present in the diffs supplied for review.
Changes:
- New Magentic orchestration sample (Program.cs, csproj, README) wiring up three agents and streaming Magentic events.
- Solution and parent README updated to register/list the new sample.
- (Per PR description, but not in the supplied diffs) Removal of
ExpectedOutput/ground-truth evaluation surface.

Motivation and Context
Ports the Python Magentic multi-agent orchestration sample to .NET, giving .NET developers a ready-to-run example of the
MagenticWorkflowBuilderpattern for coordinating specialized agents on complex analytical tasks.Description
New Magentic Orchestration Sample
Adds
