Our Extension must have a name, version, and publisher in order to be created. This information must be stored in an XML file called a Manifest.

In the Manifest XML file we can also provide more optional details as described in this MSDN reference (https://msdn.microsoft.com/en-us/library/mt600264(v=nav.90).aspx).

Now, let's focus on the minimum required fields to define our Manifest:

New-NAVAppManifest -Name "WDTU" -Publisher "CDM" -Version "1.0.0.0" | New-NAVAppManifestFile -Path "Q:WDTUManifest.xml"

The result should look something like this:

<Package xmlns="http://schemas.microsoft.com/navx/2015/manifest"> 
  <App Id="26ec7527-88b9-4b66-a77a-5a9eebbbf627" Name="WDTU" Publisher="CDM" Brief="" Description="" Version="1.0.0.0" CompatibilityId="1.0.0.0" PrivacyStatement="" EULA="" Help="" Url="" Logo="" />
