Core package includes aiohttp-specific modules under core/integration instead of aiohttp integration package

[anguzo]

Version

v4.17.0

Describe the bug

aiohttp-specific modules are included inside the core package under core/integration, which couples botbuilder-core to aiohttp despite having a separate aiohttp integration package.

Affected files:

• libraries/botbuilder-core/botbuilder/core/integration/aiohttp_channel_service.py
• libraries/botbuilder-core/botbuilder/core/integration/aiohttp_channel_service_exception_middleware.py

This placement makes the core package framework-specific instead of framework-agnostic and can force unnecessary dependencies or create version conflicts for users not using aiohttp.

To Reproduce

1. Install botbuilder-core.
2. Inspect the package contents (e.g., site-packages/botbuilder/core/integration/).
3. Observe aiohttp-specific modules present in the core package path noted above.

Expected behavior

• aiohttp-specific code lives in the aiohttp integration package (e.g., integration/aiohttp).
• botbuilder-core remains transport/framework-agnostic with clear extension points for integrations.

Additional context

Encountered while trying to integrate botbuilder into FastAPI API.
