App.xaml是应用程序的启动点（构建操作是ApplicationDefinition）。这将打开一个WinForm窗口，最终打开一个WPF窗口（单击一个菜单项时）。此时，应用程序通过WPF窗口构造函数与
崩溃The calling thread must be STA, because many UI components require this.
我尝试使用Main方法作为[STAThread]的启动点（并将App.xaml的构建操作设置为Page），但它没有帮助。 App.ApplicationStartup有[STAThread]。请注意，该项目过去只是WinForms，后来添加了WPF。
有谁知道可能的解决方案？希望这不涉及创建额外的线程。
