Tiny Devices, Big Potential: .NET & C# IoT at .NET Conf 2025 SA Johannesburg

Thank you to everyone who came out to my session at .NET Conf 2025 Community Edition South Africa in Johannesburg!

“Tiny Devices, Big Potential: .NET & C# IoT” is one of those sessions that always gets me fired up, because I get to show off what I genuinely believe is one of the coolest parts of the .NET ecosystem – .NET for microcontrollers. And Johannesburg brought the energy in a big way.

The Audience Was Amazing

The participation throughout the session was fantastic. Thank you for that! The questions, the engagement, the reactions – it made the whole experience so much fun. I really had a great time showing off .NET on tiny hardware, and having an audience that was just as enthusiastic about it made it even better.

As Promised – The Sample Code

All the sample code from the session, plus links to get started with .NET nanoFrameworkAWS IoT, and Azure IoT, can all be found here:

Session Resources and Sample Code

Here is a quick rundown of what is in there:

🌱🤖 Agricultural MCP Server Example using SSE

Build a Model Context Protocol (MCP) server on an ESP32 with a Semantic Kernel client for natural language control via LLMs. Yes – AI talking to tiny hardware. It is as cool as it sounds.

📹 Hardware-Accelerated Camera

Real-time camera streaming and image capture with nanoFramework on the ESP32-CAM. Hardware-accelerated, performant, and running C# on a microcontroller.

🎛️ Hardware Interfacing Examples

Interface with electronics and sensors using the MXChip AZ3166 development board as a practical, hands-on example. A great starting point if you are new to hardware with .NET.

Bookmark it, fork it, and start tinkering!

The DMs

I see quite a few DMs have arrived on the topic since the session. If I haven’t gotten back to you yet – I will! Looking forward to continuing the conversation around IoT, electronics, AI, and all things microcontrollers in C#.

Thank You to the Sponsors and Venue

A big thank you to all the sponsors on the day – your support makes events like this possible. And a special shoutout to BBD for providing an amazing venue to speak at. It was a fantastic space for a fantastic day.

Come Join the Tiny Revolution

If you are curious about .NET on microcontrollers – whether you are coming from a software background or an electronics background – there has never been a better time to explore it. The ecosystem is growing fast, and the intersection of .NET, IoT, and AI is one of the most exciting spaces in tech right now.

Grab the sample code, have a play, and reach out if you have questions.
