How to add image comment attribute using the ExifInterface

Hello.

I want to add comment to image When i take image in my app. I am using the media plugin to take images.
I want to store comments in the image attribute (metadata).

I came across the Exif but have no clue how to use use it.

Can someone help me with ExifInterface.

The media plugin camera code.

 `   private async void Take_Photo_Button_Clicked(object sender, EventArgs e)
    {
        await CrossMedia.Current.Initialize();
        if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakePhotoSupported)
        {
            await DisplayAlert("No Camera", ":( No camera available.", "OK");
            return;
        }

        var file = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
        {
            SaveToAlbum = true,
            Name = jobnoentry.Text + "-" + Applicationletterentry + "-" + signnoentry.Text + "-" + SignType,

        });


        if (file == null)
            return;

        MainImage.Source = ImageSource.FromStream(() =>
        {
            var stream = file.GetStream();
            return stream;
        });
