How to share a class between a background task and main App?

Question

My main App has a Class1.cs which I want to re-use in my timer background task. The background task itself trigs as as expected every 15 min, but the compiler fails when I do "Add-As-Link" on Class1.cs into the background task project. Obviously the background task class is already referenced in the main App and there seems to be a compiler conflict in App..

How can I get around this ? 

Answer 1

Thanks, I upgraded your solution to target Windows 8.1 and ran it.

But I am not sure I understand... I can't see any class being shared between the App and the background task in any direction..?

  

Answer 3

check the ClockTileScheduler class. it used in the application and in the background task

Answer 4

Sorry, you are right. It is shared from the background task to the main app

Problem is I want to share my class the other way around... How can I do this?

Answer 5

I can't get it to work with sharing code using "Add-As-Link".. But it seems possible using a Portable Class Library (DLL), maybe is this  the only way?

Answer 6

well .. that possible too .. but why want to share in different way. what kind of problem you try to solve?

Answer 7

The main App hosts class logic in order retrieve items from a server API. When the app is in the ordinary foreground mode it uses this logic. However, when the app is suspended I want a background task to share the same code in order to call the server every 15 minutes and update the tile if any new items arrives at the server end.

I gues you can compared it with updating the tile with new "Facebook status".
