What rules govern the Windows 8 store appId? Are they persistent across versions/renames?

The MSDN page for CurrentApp.appId is here.

In a typical application the property comes back in the format 00000000-0000-0000-0000-000000000000, and precisely that number if you're running an app that is not in the Windows store.

Once in the Windows store, it gets a real number, and my question is: Is there anything that would cause an appId to ever change? Perhaps as versions of the app are updated, or if the app is renamed?

The AppId will not change unless you remove the existing app and republish.

I do not have a source for this, but it is the same process from the Windows Phone Marketplace/Store. The ID is used in many places.

  • The direct link (URL) to your app
  • Used by the Store app to identify which apps have an update
  • Used by Visual Studio when creating/uploading packages
  • ...

Changing the Global Unique Identifier is totally against the point of a GUID. If it changed, many things would break. The ID does not change when updating the app, it remains the same.
