Source: Build a real-world example with Microsoft Agent Framework, Microsoft Foundry, MCP and Aspire
Observations on a Real-World AI Agent Application
The recent announcement from Microsoft, detailing a practical demonstration of the Microsoft Agent Framework integrated with Foundry, Model Context Protocol (MCP), and Aspire, caught my attention for two reasons. Firstly, it directly addresses the recurring gap between AI agent prototypes and production-grade solutions. Secondly, it answers a frequent request from .NET developers: an open-source example that operates both locally and in cloud-native environments.
As someone who has observed several AI frameworks emerge and fade, I find the launch of the Interview Coach sample app notable for its pragmatism. This is not another “Hello World” but a functioning application that tests agent orchestration, persistent state, middleware integration, and enterprise features such as OpenTelemetry. These are precisely the issues technology leaders wrestle with when transitioning AI from proof-of-concept to business-critical deployments.
Strategic Reflections on Microsoft’s Approach
From a leadership perspective, Microsoft’s consolidation of agent development into the new Agent Framework is significant. The framework unifies concepts from Semantic Kernel and AutoGen while adding features aimed at real-world scalability: dependency injection, familiar ASP.NET hosting models, multi-agent orchestration patterns and telemetry. For organisations invested in .NET, this means reduced cognitive load—one framework to learn instead of two—and greater consistency across applications.
The integration with Microsoft Foundry is equally meaningful. Foundry acts as an abstraction layer for model access (across OpenAI, Meta and others), content safety via moderation tools, cost optimisation through routing and enterprise governance using Entra ID. This suggests Microsoft is positioning itself not just as a toolkit provider but as an opinionated platform for deploying responsible AI at scale. However, there are questions around lock-in versus flexibility: while IChatClient makes model switching straightforward in principle, deep integration with Azure services could tie architecture choices closely to Microsoft’s ecosystem.
One aspect I am keenly interested in is how these building blocks—Agent Framework, Foundry, Aspire—will influence cross-cloud portability and open standards adoption in AI workflows. The use of MCP hints at interoperability but the long-term outcomes remain to be seen.
Looking Ahead
In summary, this real-world sample marks an important step in operationalising AI agents beyond experimentation for .NET shops. It brings together proven engineering practices with modern cloud-native patterns. Yet as always with new frameworks, I would advise technology leaders to weigh architectural dependencies carefully and stay attentive to evolving standards outside the Microsoft stack.
