任何人都可以提出的方法，將允許我從ElementHost中的WPF元素更改主機WinForm的屬性嗎？從ViewModel綁定到ElementHost更改主機WinForm屬性
我必須使用綁定到一個ElementHost的棱鏡的MVVM應用程序。我想更改WinForm標題，調整WinForm的大小並關閉我的ViewModel中的WinForm。
我明白從this article中描述的WPF複合控件接收數據，但我無法看到這將在ViewModel中如何工作。
應用程序是WinForm ChartWizardViewModel是ViewModel我想更改應用程序的屬性。 其他一切都是棱鏡架構。殼，引導程序等。

Dim formBootstrapper As New Bootstrapper(modulesToLoad)
