This feature is probably available in case of other kinds of projects (Windows Forms, for example). In WPF you can use the dialog programmatically. (Short example in C# and VB: https://learn.microsoft.com/en-us/dotnet/desktop/wpf/app-development/dialog-boxes-overview). You can find some samples for IronPython too, but use Microsoft.Win32.OpenFileDialog instead of System.Windows.Forms.OpenFileDialog.

Hello, I created a wpf project in Visual Studio with IronPython. For some reason, I don't a OpenFileDialog in my toolbox, I even go to "Choose ToolBox Item" to see if I have it. Turns out I do have it but it still not appear in my toolbox after I put a check mark on it. Any suggestions will be appreciated.
