Does WP8 DeviceStatus.ApplicationCurrentMemoryUsage Property take into acount native allocations?

Question

I can't find this specified in the documentation, so I'm wondering if anyone has any experience regarding this?

I need to know about all the memory the application is consuming, therefor a sum of what was allocated in the native project I'm referencing and what is managed in the managed application.

The documentation I'm looking at can be found at: http://msdn.microsoft.com/en-us/library/windowsphone/develop/microsoft.phone.info.devicestatus(v=vs.105).aspx

Bonus: While we are at it, can I find out how much memory is allocated to each part of the application (native vs managed)?

Answer 1

Yes, DeviceStatus.ApplicationCurrentMemoryUsage does include the total memory the application is using: both Native and Managed.

You can ask GC.GetTotalMemory how much managed memory it thinks is used, but I've found that this isn't reliable.

As per MSDN:

Retrieves the number of bytes currently thought to be allocated.

Update:

There is a brief example of how to determine how close you are to your memory limits at DeviceStatus.ApplicationMemoryUsageLimit Property, but it doesn't explicitly call out different types of memory. I suspect that is as close as you are going to get to a reference at MSDN for now.
