What does "m2" mean in XAML?

Question

In in the Package.appxmanifest file in my Windows Store app I noticed it has:

<m2:VisualElements DisplayName="NameOfApp"/>

Does anyone know what the m2 means?

At the top of your manifest should be something similar to this...

<Package xmlns="http://schemas.microsoft.com/appx/2010/manifest" xmlns:m2="http://schemas.microsoft.com/appx/2013/manifest">

The m2 points to the namespace schema defined by the URL http://www.w3schools.com/xml/xml_namespaces.asp

m2 is an xml namespace alias.

Specifically, m2 is generally used to refer to extensions added to the 2013 version of the schema:

xmlns:m2="http://schemas.microsoft.com/appx/2013/manifest"

To distinguish it from the version used as the default namespace:

xmlns="http://schemas.microsoft.com/appx/2010/manifest"
