如何在F＃源文件中继承Window类

Question

When scripting it's done like:

#light 
#r "System.Xaml.dll"
#r "WindowsBase.dll"
#r "PresentationCore.dll"
#r "PresentationFramework.dll"

open System
open System.Windows

let win = new Window()
win.Title <- "Say Hello"
win.Show()

#if COMPILED
[<STAThread()>]
do 
    let app =  new Application() in
    app.Run() |> ignore
#endif

Beneath text for a source file, where I've added System.Xaml, WindowsBase, PresentationCore and PresentationFramework to my references.

open System
open System.Windows

let win = new Window()
win.Title <- "Say Hello"
win.Show()

#if COMPILED
[<STAThread()>]
do 
    let app =  new Application() in
    app.Run() |> ignore
#endif

I get the message: The type "Window" is not defined. Can anybody tell me how to acces / reference the namespaces System.Windows and System.Windows.Controls from a source file?

Thanks

EDIT: Added screenshot

Before going any further I want to turn the script (with UI) into a source file.

Answer 1

1. In Solution Explorer, select the project. On the Project menu, click Add Reference. Or: Project -> Add Reference

2. The Add Reference dialog box opens. Select the tab indicating the type of component you want to reference.

Choose:

WindowsBase.dll
PresentationCore.dll
PresentationFramework.dll
System.Xaml.dll

Or download template:
