无法在F#FSI的WPF文本框中输入文本

在下面的F#WPF代码中，当我从F#FSI“显示”WPF窗口时，我无法在文本框中输入任何文本。这与正在使用的Windows窗体事件循环有关吗

let txtBox = new TextBox()
txtBox.BorderThickness <- Thickness(2.)
txtBox.Margin <- Thickness(7.)
txtBox.IsReadOnly <- false

let wnd = new Window(Title = "Test", Height = 500., Width = 500.)
wnd.Content <- txtBox
wnd.Show()

让txtBox=newtextbox（）
txtBox.BorderThickness您需要调用
应用程序。运行
-请参阅。这将自动为您启动事件循环

let txtBox = new TextBox()
txtBox.BorderThickness <- Thickness(2.)
txtBox.Margin <- Thickness(7.)
txtBox.IsReadOnly <- false

let wnd = new Window(Title = "Test", Height = 500., Width = 500.)
wnd.Content <- txtBox

(new Application()).Run(wnd) |> ignore
