Intune device get DetectedApps via Graph (different results for different methods)

Question

Trying to obtain DetectedApps via Graph.

DeviceManagement.ManagedDevices[deviceId].DetectedApps.Request().GetAsync() - 17 items as a result

(DeviceManagement.ManagedDevices[deviceId].Request().Expand(d => d.DetectedApps).GetAsync()).DetectedApps - 63 items as a result

Why do we have such a difference?

Answer 1

@Vladimir Tataurov, Thanks for posting in Q&A. The reason for the difference in the number of detected apps obtained through the two methods is due to the difference in the way the data is queried.

The first method DeviceManagement.ManagedDevices[deviceId].DetectedApps.Request().GetAsync() returns only the detected apps for the specific device ID provided, whereas the second method (DeviceManagement.ManagedDevices[deviceId].Request().Expand(d => d.DetectedApps).GetAsync()).DetectedApps returns all the detected apps for the device ID provided and any related devices.

Therefore, the second method returns a larger number of detected apps as it includes those detected on related devices.
