如何在 Visual Studio 中将 Windows.Forms 框架添加到 WPF 项目

Question

I"ma complete noob in Visual Studio. I'm trying to write a simple app using WPF. I need a dialog that would pick a folder. I know that WPF doesn't have one, and I need to use Windows.Forms with their FolderBrowserDialog. I need to add Widnows.Forms framework to references so that I could say using System.Windows.Forms; and then just do this dialog. However when I'm trying to follow the instructions, I do not see any Windows.Forms here, except for what's on the image. And even if I add those, it still doesn't take using System.Windows.Forms; What should I do?

Answer 1

1. First create a .Net6 Wpf project
2. Double-click the project to enter csproj and manually add the following code:

<UseWindowsForms>true</UseWindowsForms>

3. Manually enter the following new folderbrowserdialog code, and then use intellisense to automatically add using System.Windows.Forms; That's it (you can also add it manually)

FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();

3. call it

private void Button_Click(object sender, RoutedEventArgs e)
{
  using FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
  {
    folderBrowserDialog.ShowDialog();
  }
}

4. You can also go to Property -> Application -> General -> Windows Forms -> Enable Windows Forms for this Project in the .net6 project.
