.NET Assistive OBO WorkIQ wiring fails build: AgentThread type missing #64

Summary

The Group E .NET Assistive OBO path fails to build after the WorkIQ wiring step. The generated/modified agent code references AgentThread, but that type is not available in the resolved Microsoft Agents SDK package set.

Scenario

• Scenario: Group E, .NET AgentFramework Assistive OBO
• Prompt: "Register this as an Agent 365 Assistive agent with auth mode OBO"
• Expected path: a365-setup -> make-a365-agent -> instrument-observability -> add-workiq-tools -> test-local
• Auth mode: obo
• Capabilities: Register + Observability + WorkIQ

Environment

• OS: Windows
• .NET SDK: 9.0.314
• a365 CLI: 1.1.184
• Agent 365 skills plugin version: 1.0.1

What succeeded before the failure

• a365 setup all --authmode obo --agent-name WeatherAgentAssistive created/stamped config
• Observability wiring was attempted
• WorkIQ package restore initially hit version conflicts; after package updates restore succeeded
• WorkIQ service registration and ToolingManifest steps were attempted

Actual build failure

Running:

cd C:\bugbash\runs\E-dotnet-assistive-obo
dotnet build --no-restore

produces:

Agent\WeatherAgentApp.cs(295,20): error CS0246: The type or namespace name 'AgentThread' could not be found (are you missing a using directive or an assembly reference?)
Build FAILED.
0 Warning(s)
1 Error(s)

Expected

The .NET OBO Assistive path should leave the project building successfully after observability and WorkIQ wiring, so test-local runtime validation can proceed.

Impact

Runtime validation is blocked for .NET Assistive OBO:

• agent cannot start
• observability runtime cannot be verified
• WorkIQ runtime cannot be verified
• notification applicability cannot be assessed beyond "Assistive has no M365 notification surface"

Notes

The skill-generated code appears to assume an AgentThread type from a prior or different SDK surface. The resolved packages in this run included Microsoft.Agents.AI / Abstractions 1.1.0 after package reconciliation.
