有没有办法在LinqPad中实例化实例化WPF对象?这是我的例子(在查询中添加了正确的程序集等):
var w = new Window();
w.Loaded += (o,e) => {
w.Content = new TextBlock() { Text = "Foo" };
};
w.Show();
然而,这死于可怕的死亡:
System.Runtime.InteropServices.InvalidComObjectException: COM object that has been separated from its underlying RCW cannot be used.
at System.Windows.Input.TextServicesContext.StopTransitoryExtension()
at System.Windows.Input.TextServicesContext.Uninitialize(Boolean appDomainShutdown)
at System.Windows.Input.TextServicesContext.TextServicesContextShutDownListener.OnShutDown(Object target, Object sender, EventArgs e)
at MS.Internal.ShutDownListener.HandleShutDown(Object sender, EventArgs e)
有关如何使其发挥作用的任何线索?

另一种方法如下:
w.ShowDialog();
Dispatcher.CurrentDispatcher.InvokeShutdown(); // Cleanly end WPF session.
更多例子:
new Window { Content = "Foo" }.ShowDialog();
new Window { Content = new Button { FontSize = 50, Content = "Foo" } }.ShowDialog();
Dispatcher.CurrentDispatcher.InvokeShutdown(); // Cleanly end WPF session.

您需要通过调用new Application().Run(w)
来运行消息循环。
