Synchronization to a shared resource, e.g. a file, between background task and app

Question

What would be a good way of doing this?

Answer 1

depends on how much data, and are your shared resources in the same app package or in different packages?

Answer 2

A few k of data, so small, and the same package.

Answer 3

ApplicationData.Current.LocalSettings for just settings and ApplicationData.Current.LocalFolder for files would be the best approach

Answer 4

Dave thanks, I should have been a little clearer in the question. - This is concerning synchronization of access, these are good examples of where the file or data is stored.

The app and the background task could attempt to read/write to the same resource at the same time. What would be a good way to manage this thread synchronization to the resource?

Answer 5

a mutex should do the job for this:

for phone this worked, for windows I never tried out but seems to be supported in a store app so guess it should work here too

Answer 6

This is the same line as my thinking, because it is inter-process.

There is a named Semaphore.

Both could, in theory be right.

Ta.

Answer 7

for Semaphore you can better use SemaphoreSlim http://msdn.microsoft.com/en-us/library/system.threading.semaphoreslim(v=vs.110).aspx

but this one shouldn't be Inter-process. so mutex should be the way to go
