使用WinForms窗口启动WPF应用程序

Question

I have WPF application with some WPF windows. But my main window is WinForms and I need to start program with it. But how can I do this? This is my App.xaml file:

<Application x:Class="Player.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="UI/MainWindow.xaml">
    <Application.Resources>
    </Application.Resources>
</Application>

If I try to replace StartupUri="UI/MainWindow.xaml" with StartupUri="UI/Form1.cs" , I get "System.IO.IOException", "Cannot find "ui/form1.cs" . Is it even possible to start my app with WinForms window?

Answer 1

First go to App.xaml and remove StartupUri="UI/MainWindow.xaml" . Than go to App.xaml.cs and override OnStartup method. In there you can instantiate and run your win forms window.

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);
    var form = new Form1();
    form.Show();
}

There is a good article from MSDN which provides you an example how to integrate an Windows-Forms element in XAML: https://msdn.microsoft.com/de-de/library/ms742875(v=vs.110).aspx
