Building Cross-Framework Agents with MAF, A2A, NVIDIA NeMo, and Aspire

This article presents a production-ready sample application that demonstrates how to build cross-framework AI agents using NVIDIA NeMo Agent Toolkit, Microsoft Agent Framework (MAF), Agent-to-Agent (A2A) communication protocol, and Aspire orchestration. The scenario involves a Python-based NeMo data analysis agent and a .NET-based MAF action agent working together via A2A (JSON-RPC) for enterprise workflows like data analysis, anomaly detection, alerting, and reporting. Aspire provides health checks, service discovery, tracing, and startup orchestration. The article emphasizes separation of concerns, scalability, and vendor flexibility without requiring a single framework rewrite.
