I'm missing a proper WPF-way to select a folder with a dialog.

Best answers on the internet says I have to reference WinForms and use the FolderBrowserDialog. I don't want to make a reference to WinForms just to make a dialog to select a folder.

WPF already have SaveFileDialog and OpenFileDialog...
