Background task and write to isolated storage

Question

I try my best to write to isolated storage in my background task. The reason for this is that at every start of the background task I load data, and I need to compare this data the next time the background task starts. If the data has been changed, a toast notification is displayed.

The problem is that the data that I write to isolated storage is not saved. I can use it in the rest of the OnInvoke function, but the next time the background task starts, there will be no value.

Am I missing something, I thought it would be easy?

EDIT: Reading values ​​works very well, and writing values ​​from my main application also works fine. The code I use in my OnInvoke function is this:

IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings; settings["WebValue"] = gtResult[i]; 

Answer 1

Maybe settings.Save(); should do it?
