Hello,
Do we have any way to check or monitor the activeness of any layer or component in any WPF application ? I heard about WatchDog mechanism to use for this purpose but couldn't get any proper information.

My Scenario -

ComponentOne (ClassLibrary)
||
|| reference being used in ComponentTwo
V
ComponetTwo (ClassLibrary)
||
|| reference being used in ComponentThree
V
ComponentThree (.exe/view)

On view i want to show the health of above two component something like Active-if everything is fine, Dead- if any Thread is aborted etc.
we need to introduce a mechanism that the GUI knows if the Interface is still intact/alive/responding etc.

What I have tried:

Read about WatchDog but no luck

From what you have written here it's not possible to get the context of your problem. But in general: "a mechanism … if the interface is still active" can be created - you are programming so just create a mechanism. Maybe one can help if you tell us your concrete problem, not just some vague "monitor" - it could work from pings, to message-loop inspection or just some events, or a statemachine…. monitor could mean anything...

+ btw. from what you have written it just sounds that you don't have good error handling in place - so first I'd question your need for this "monitor" - add just proper error/exception handling...

Solution 1

Use Dispatcher.Timer(s) to execute code at certain intervals that checks the "health" of your system; e.g. connection status; other threads; user (in)activity.
