Question

I have a class library which is a set of helper classes to develop windows phone 7 applications.

One of core helper classes I have in this library is responsible to provide location service functionalities, so it uses ILocationWatcher and references to System.Device.

Now the problem is even if I don’t use this helper class (i.e. LocationWatcher will never be started) after submitting the app in marketplace, it shows “Location services” as one of capabilities my app is using.

I believe the way marketplace detects this, is more or less analysing all codes and libraries within the project.

How can we somehow override this behaviour?

Answer 1

Capabilites are detected using static analysis when your xap is submitted to the marketplace.

The location capabiltiy is reported if you reference the assembly System.Device and use the namespace System.Device.Location.

All assemblies in your XAP are analysed. Even ones you get from 3rd parties.

If you don’t want the capability to be reported in the marketplace then remove the references which triggers its detection.
You may want to consider how you structure your shared/common libraries/code with this in mind.
