How can I send messages from wpf to iot device edge module

Reem Fatahalla 26

I am new to IOT Edge, still going through the tutorial.
I would like to know if I can make a wpf application send/receive messages with IOT Edge module? and how

Welcome to Microsoft Q&A and IoT Edge Development @Reem Fatahalla !

Can you share more detail on what you are trying to achieve? If you would like to develop IoT Edge Modules with C# language here is the tutorial: Develop a C# IoT Edge module for Windows devices

Note: IoT Edge modules are containers that run Azure services, third-party services, or your own code. Modules are deployed to IoT Edge devices and execute locally on those devices.

Please help us understand better what you mean with a wpf application sending and receiving messages with IoT Edge module.

Thanks for your reply,

We already have WPF application which communicate with devices and running the UI needed, I need to bring the data the WPF application read into cloud,
We are planning to have more modules communicating some sensors/devices and need this data to be sent to the wpf application and cloud, my idea is to use Iot edge devices to read the data coming from the sensors/devices and send it to the wpf and to cloud, the use of iot edge will make the whole system able to run and communicate when there is no internet connection, and that's why I can not just make wpf send data to iot hub and communicate back with the other modules.

As @António Sérgio Azevedo explained, there are two options:

1 You manage to host your WPF application in a docker container

In that case, you need to attach to the routing system inside the docker container using the Azure SDK. Take a look at this example of a similar approach to connect a Blazor app to the IoT Edge routing.

2 You run a WPF somewhere on the same network and try to reach the IoT Edge to send data to the cloud

In this case, something on the edge needs to expose an endpoint so the incoming messages can be routed towards the cloud. In the past, I experimented with a nodejs module which exposed a SocketIO server.

Thanks a lot for your replay and sorry for the late respond as I keep looking at the two examples that you did and trying to produce the same as wpf, but I also found that wpf can not running in a container, I am a bit confused.
also not sure how to build and publish the application to docker.
sometimes think to create a WCF run it in Iot edge and make it talk to the WPF
