IoT DevTool is not a Microsoft official project.

A series of posts to introduce IoT DevTool:

  1. Overview
  2. For Cloud Developers
  3. For IoT Hub Device Administrators
  4. For Device Developers
  5. For RESTful Developers

Connect to IoT Hub

Before you start you need a connection string with registry read & write permission. You can find it from Device Explorer tab in IoT Hub dashboard.

      Hi Satya, thanks for your interest in IoT DevTool!

      Yes, we have published IoT DevTool source code to GitHub (https://github.com/VSChina/IoT-DevTool/), you can deploy it to your own server!

      However, we still need to do more work to make it easy to deploy to other server.

      If you do not want to wait, you can do some extra work yourself.

      Change REST API proxy. Because Azure IoT REST API doesn’t support CORS yet, you need host a proxy to handle RESTful request, also you need change REST API domain in the code.
