New one that is driving me batsh-t.

This code:

 DockPanel.create [
      DockPanel.children [
        TabControl.create [
            TabControl.dock Dock.Top
            TabControl.tabItems (
                state.plugins
                |> List.map (fun pluginRec ->
                    TabItem.create [
                        TabItem.header pluginRec.Name
                        TabItem.content (
                            pluginRec.Instance.View state pluginRec.State
                                (fun (msg: IPluginMsg) ->
                                    dispatch (ShellMsg.PluginMsg msg :> obj))
                        )
                    ]
                )
            )
        ]
    ]
]

Produces this error:
Error FS0039 : The value, constructor, namespace or type 'children' is not defined.
on the line DockPanel.children.

These are my opens:

open System
open System.IO
open System.Reflection
open Elmish
open KankasaurPluginSupport
open KankasaurPluginSupport.SharedTypes
open Avalonia.FuncUI.DSL

Ive asked github co pilot and it gives me the same code back. I looked at an example DockPanel and it looked identical to me.
