C# can be used for AR development in conjunction with platforms like Unity3D. However, for a quick web-based AR experience, you can use AR.js, which is based on JavaScript and A-Frame.

Sample AR Code

Here's a basic example of AR.js usage:

<script src=`https://aframe.io/releases/1.2.0/aframe.min.js`></script>
<script src=`https://cdn.rawgit.com/jeromeetienne/AR.js/2.0.8/aframe/build/aframe-ar.js`></script>
<a-scene embedded arjs>
  <a-marker preset=`hiro`>
    <a-box position=`0 0.5 0` material=`color: red;`></a-box>
  </a-marker>
  <a-entity camera look-controls></a-entity>
</a-scene>
    

This code creates a simple AR scene where a red box is displayed when the Hiro marker is detected.

Conclusion

C# can be utilized for AR development in the context of platforms like Unity3D with AR Foundation. For web-based AR experiences, you can use libraries like AR.js, as shown in the sample code. Full-fledged AR development involves creating interactive 3D models, integrating with real-world objects, and much more.
