Currently, the FileSavePicker allows setting detailed file extensions using the FileTypeChoices property, as demonstrated below:

picker.FileTypeChoices.Add("Images", new string[] {".jpg", ".png" });

However, the FileOpenPicker relies on the FileTypeFilter property, which only accepts extensions without additional details. Introducing a FileTypeChoices property for FileOpenPicker would enhance its functionality by enabling the inclusion of detailed file extension descriptions.

Also for the question 4: It's an inspiring request to add FileTypeChoices for the FileOpenPicker. While it might not be implemented in this release, if it can be helpful, do please suggest it in our feedback wanted section.

@DinahK-2SO yes, by all means. I also believe that other developers also want this.
