How to open the "Open With" dialog (Windows Store App)?

Question

I want my app to let a user open a file with the "Open With" dialog even if it has a default application that opens that type of file. How can I achieve that?

Answer 1

Call Launcher.LaunchFileAsync and set LauncherOptions.DisplayApplicationPicker to true:

var options = new Windows.System.LauncherOptions();
options.DisplayApplicationPicker = true;

bool success = await Windows.System.Launcher.LaunchFileAsync(file, options);
