Currently, the Agent Framework lacks built-in support for vector databases, which are essential for RAG patterns in production agent systems.

Proposed Enhancement:

Add first-class connectors for popular vector databases:

Azure AI Search (given Azure ecosystem focus)
Pinecone
Weaviate
Qdrant
Chroma
PostgreSQL with pgvector

Include built-in retrieval patterns:

Semantic search tools for agents
Hybrid search (vector + keyword)
Re-ranking capabilities
Metadata filtering
