IntelliSense missing GridViewColumn type

Hi all

 Has anyone else noticed in the visual studio powershell WPF project the IntelliSense doesn't recognise GridViewColumn within a list view like so:
<ListView>
      <ListView.View>
          <GridView>
               <GridViewColumn/>
          </GridView>
      </ListView.View>
</ListView>

Is this a bug? As the gui runs fine, it’s just IntelliSense that moans about it.

Tool: Visual Studio, PowerShell Module
Version: 2019

I found the cause of this, when you add a WPF PowerShell window it doesn’t add this reference:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.7.2\System.dll
