WP7 app version

Question

A Windows Phone 7 app, it seems, has two places with version number - one in AssemblyInfo.cs (via AssemblyVersion/AssemblyFileVersion attributes), the other is WMAppManifest.xml. Those two seem uncorrelated - changing one does not affect the other. The Marketplace, it seems, uses the one from the manifest - can someone please confirm this?

The real question is - how do I retrieve the one from manifest programmatically to display on the About screen?

Answer 1

The WmAppManifest.xml number is in use. First two digits are relevant for Marketplace (it is checked when you do the update) next two are for your internal usage.

This is a regular XML file, open it as a XDocument and parse it. An example.

EDIT: the example is extraneous. For just the version, use:

string Version = XDocument.Load("WMAppManifest.xml")
    .Root.Element("App").Attribute("Version").Value;
