任何人都可以提出的方法，将允许我从ElementHost中的WPF元素更改主机WinForm的属性吗？从ViewModel绑定到ElementHost更改主机WinForm属性
我必须使用绑定到一个ElementHost的棱镜的MVVM应用程序。我想更改WinForm标题，调整WinForm的大小并关闭我的ViewModel中的WinForm。
我明白从this article中描述的WPF复合控件接收数据，但我无法看到这将在ViewModel中如何工作。
应用程序是WinForm ChartWizardViewModel是ViewModel我想更改应用程序的属性。 其他一切都是棱镜架构。壳，引导程序等。
