Bug: pip resolution failure in hosted agent samples — agent-framework meta-package pins conflicting agent-framework-core versions

[VBhadauria]

Bug

Affected: 13 of 16 hosted agent response samples (samples/python/hosted-agents/agent-framework/responses/)
Impact: Hosted Agent quickstart is broken, blocking Tracing + Evaluate quickstarts downstream.

Root cause

requirements.txt in most samples uses:

agent-framework>=1.2.2
agent-framework-foundry-hosting

When pip resolves agent-framework to 1.2.2, it pins agent-framework-core==1.2.2. But agent-framework-orchestrations 1.0.0 (a transitive dep) requires agent-framework-core>=1.9.0. Pip cannot satisfy both:

ERROR: Cannot install agent-framework-core and agent-framework-core[all]==1.2.2
  agent-framework 1.2.2 depends on agent-framework-core==1.2.2
  agent-framework-orchestrations 1.0.0 depends on agent-framework-core>=1.9.0
ERROR: ResolutionImpossible

Samples already fixed (working pattern)

Samples 11-azure-search-rag, 12-foundry-skills, and 13-foundry-memory already work around this by using agent-framework-foundry (narrow subpackage) instead of the agent-framework meta-package.

Proposed fix

Replace agent-framework / agent-framework[foundry]>=1.2.2 with agent-framework-foundry in all 13 affected samples. Also add mcp>=1.24.0 where missing (runtime dep not declared by agent-framework-core).

A complete branch with the fix is available at: https://github.com/VBhadauria/foundry-samples/tree/fix/requirements-dep-conflict

Affected samples

Sample	Current requirements	Status
01-basic	agent-framework>=1.2.2	❌ broken

03-mcp	agent-framework>=1.2.2	❌ broken
04-foundry-toolbox	agent-framework[foundry]>=1.2.2	❌ broken
05-workflows	agent-framework>=1.2.2	❌ broken
06-files	agent-framework (bare)	❌ broken
07-skills	agent-framework>=1.2.2	❌ broken

Verification

Tested all 13 samples with pip install --dry-run (Python 3.13):

• Before (agent-framework==1.2.2): ❌ ResolutionImpossible for all 13
• After (agent-framework-foundry): ✅ Resolves cleanly for all 13
