I have created an IoT Hub Edge device. In the beginning, the default $edgeAgent and $edgeHub modules went in. That's fine. Then I added a "barkModule" (note the lower-case B at the start) -- just a test module to play with D2C event messages and DirectMethod calls to the module.
Later on, I removed that module and added a new one, this time with BarkModule (capital B). Been rocking this way for about a week.
I did this bit of code to get a list of a devices module twins (_deviceTwins is the twins of all the devices on the hub, this is basically just getting all the modules for the device) :
foreach (var _device in _deviceTwins) {
var moduleList = await registryManager.GetModulesOnDeviceAsync(_device.DeviceId);
DeviceList.Add(new DeviceAndModules { DeviceTwin = _device, Modules = moduleList.ToList() });
};
In its module twin list -- I'm getting an entry for both BarkModule and barkModule. Even though my device just has $edgeAgent, $edgeHub and BarkModule modules.
I even went digging in $edgeAgent's module twin, and there's a ton of meta-data event history stuff (seriously, this is absurdly large) -- but there's NO reference to the lowercase-b "barkModule" anywhere.
How is it maintaining this information? Why is this showing up still? Is there a way I can remove this?
This shows the modules:
This shows there's only three:
