FileSavePicker task not showing in Window.Storage.Pickers in wp8 c#

Question

I'm trying to save a video file using FilePicker Task but its not showing FileSavePicker task in Solution. Below a screen shot is attached

There are only 4 tasks showing in Windows.Storage.Pickers

1. FileExtensionVector
2. FileOpenPicker
3. PickerLocationId
4. PickerViewMode

Here is code I'm using

        async void TrimVideoFile()
    {
        Windows.Storage.StorageFile source;
        Windows.Storage.StorageFile destination;

        var openPicker = new Windows.Storage.Pickers.FileOpenPicker();

        openPicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.VideosLibrary;
        openPicker.FileTypeFilter.Add(".wmv");
        openPicker.FileTypeFilter.Add(".mp4");

        source = await openPicker.PickSingleFileAsync();

        var savePicker = new Windows.Storage.Pickers.FileSavePicker()
        savePicker.SuggestedStartLocation =
            Windows.Storage.Pickers.PickerLocationId.VideosLibrary;

        savePicker.DefaultFileExtension = ".mp4";
        savePicker.SuggestedFileName = "New Video";

        savePicker.FileTypeChoices.Add("MPEG4", new string[] { ".mp4" });

        destination = await savePicker.PickSaveFileAsync();

        // Method to perform the transcoding.
        TrimFile(source, destination);
    }

Its showing only 4 tasks. What to do to use FileSavePicker task. I'm using Visual Studio 2012 and my targeted app is Windows Phone 8.0 App.

File pickers are not available on Windows Phone 8. They were added with Windows Phone 8.1.

See the Version section in the FileSavePicker docs on MSDN:

Minimum supported phone Windows Phone 8.1 [Windows Phone Silverlight 8.1 and Windows Runtime apps]
