Post series – Building .NET applications that consume Azure AI Foundry Agents

[TallesValiatti]

Introduction

Hi everyone 👋

I recently published a multi-part series on my personal blog showing how to build a real .NET application that consumes Azure AI Foundry Agent Service in production-oriented scenarios.

Across the series, I cover topics such as:

• Integrating Azure AI Agent Service with File Search
• Consuming Function Calling with agents
• Call external web APIs through OpenAPI Specification
• Connecting with Azure AI Search Service
• End-to-end implementation examples based on real-world production setups
  …and others.

Here are the posts:

• Part 1: Creating an application with Azure AI Agent Service – Part 1
• Part 2: Creating an application with Azure AI Agent Service – Part 2
• Part 3: Creating an application with Azure AI Agent Service – Part 3
• Part 4: Creating an application with Azure AI Agent Service – Part 4
• Part 5: Creating an application with Azure AI Agent Service – Part 5

The posts were written in pt-BR, as they were aimed at my local community here in Brazil, but they can be easily translated into en-US. At the end of each post, I also share a GitHub repository so readers can clone the code and follow along.

I’m from Brazil 🇧🇷, and you can find me on LinkedIn. I’m always speaking about agents built in .NET with Azure AI Agent Service — both here in Brazil and in the USA.

Furthermore, I hope this helps anyone looking to integrate .NET applications with Azure AI Foundry Agents 🚀

Features and Screenshots

Technical Details

Tech stack: .NET (C#), ASP.NET Core, EF Core, Azure AI Foundry SDK for .NET, and others
Azure services: Azure AI Foundry Agent Service, Azure AI Search, Azure App service, and others

Challenges and Solutions

During development, one of the biggest challenges was to simulate real-world scenarios while keeping the solutions production-ready. To address this, I created applications that mirrored real-world use cases, showing how .NET integrates with Azure AI Foundry Agents in practice. I used Azure resources to solve common problems such as file search, function calling, and scaling. My goal with the articles is to help students, professionals, and others understand these concepts and learn how to consume Azure AI Agent Services more effectively.

@TallesValiatti - Thank you for sharing! examples of use cases in different languages of using Foundry services is really valuable for developers. As a hint for others I went to this overall medium page and my Edge browser automatically asked if I would like to translate to English https://medium.com/@talles.dsv

@amynic Thank you! Glad to hear it was helpful 🙌
It’s good to know the content can be easily translated. I have many other topics lined up that I’ll be sharing here soon as well.
