I am not able to get the GeofenceMonitor rising any event; neither StatusChanged nor GeofenceStateChanged.
I am developing for Windws 10 - Build 14393.
Does it maybe depend on the device? Are there any hidden system settings that I have to enable first?

I'm developing a line of business app for Windows 8.1, that is, I am not deploying through the Windows Store and will be able to control all of the features of both the OS and hardware this app is being deployed on.
Because this app is working as the UI in a real-time situation I would prefer if I could ignore the life-cycle events and not have the app suspend or terminate at the whim of Windows 8. Does anyone know of a way to do this?
I have seen some older answers, such as this one and this other one indicating otherwise, but I haven't yet found anything more recently and specifically dealing with the case of a line of business app. I have found the Embedded Lockdown Manager which would prevent the app losing focus and addresses some of the needs I have, but I still would like a way to simple disable Lifecycle events.
Have you tried Assigned Access Mode? Basically use PC Settings -> Accounts to lock an account to a single app. You have to reboot the device and log-in again in order to run anything else.
I am developing a Windows phone 8 app that need to run only in background with UI. Is there any way I can run the app in the background, or without actually being open?
It depends upon what you want to do in the background. Generally speaking you can't implement something like a Windows service that will startup automatically when the phone is launched.
That said you can run your app in the background within given limitations. Check out MSDN for detailed information.
Why all these limitations you might ask yourself? It's to provide a good battery life to the user.
Edit:
For the periodic agent to start running the app must be started once. Further the agent must update a live tile (user must pin it to the start screen) or the app has to be once opened every 14 days.
Another option might be using push notifications to trigger an update..
I'm in the process of developing a WP8 app that makes use of the background location tracking abilities provided by the OS. The idea is to monitor the users position and to notify them when they are near certain types of places.
So far it all seems to work fine and when running the location tracking works as I would expect.
The problem is, it seems that the phone times out background apps after around four hours, stopping the location tracking.
I can understand why Microsoft did it, to preserve battery life etc. But there's not much point having a background location tracking app that has to be manually restarted every four hours! If a user chooses to run this app and is made aware of the potential battery hit, surely it should be able to run indefinitely - to a point of course, if the system runs out of resources or similar then that's fair enough.
Does anyone have any experience with this? There must be hundreds of others apps in the store that have run into this issue I would have thought? And presumably there must be some way of keeping the location tracking running?
I've tried periodically updating the live tile (using a DispatcherTimer) while the tracking is running but this doesn't seem to be enough to keep the app alive either :(
Anyone have any ideas?
Thanks.
There is no way to achieve your desired behavior. The app will be deactivated under anye of following conditions:
The app stops actively tracking location. An app stops tracking location by removing event handlers for the PositionChanged and StatusChanged events of the Geolocator class or by calling the Stop() method of the GeoCoordinateWatcher class.
The app has run in the background for 4 hours without user interaction.
Battery Saver is active.
Device memory is low.
The user disables Location Services on the phone.
Another app begins running in the background.

What you could do is to show a toast notification before app is deactivated advising the user, and make him navigate back to the app, extending the period for other 4 hours that way.
There is no way to keep it running without any user interaction.
I want to create a HTML5 Application on a Windows 8 Computer which provides product information for a user in the store. Does anyone know if it is possible to set up the windows 8 in a such away, that the user cannot exit the HTML5 App?
This isn't possible on Windows 8; the soon to be released Windows 8.1 has a "Kiosk Mode", which seems to be what you are looking for. From Windows 8.1 kiosk mode locks systems to a single app:
Generally speaking, kiosk mode is something that’s intended for use in corporate and shared computing settings — like public information terminals. It would, for example, make an excellent way to lock a point-of-sale terminal in to the “cash register” app and prevent would-be procrastinators from tabbing out and surfing the web.
When I run my windows phone 8 app, the system tray only shows the clock and battery indicators. In some cases, I'd like to show the cell signal strength and the wifi indicators for a few seconds, in order to remind the user that s/he's offline.
The only way I can do this currently is when the user taps on the System Tray area, but I'd like to show those programmatically. Is this possible ?
I am not sure if it's possible, but you could show it on your app.
