The easist and flawless solution I found is to use MediaToolkit nuget package.

using MediaToolkit;

// a method to get Width, Height, and Duration in Ticks for video.
public static Tuple GetVideoInfo(string fileName)
{
    var inputFile = new MediaToolkit.Model.MediaFile { Filename = fileName };
    using (var engine = new Engine())
    {
        engine.GetMetadata(inputFile);
    }

    // FrameSize is returned as '1280x768' string.
    var size = inputFile.Metadata.VideoData.FrameSize.Split(new[] { 'x' }).Select(o => int.Parse(o)).ToArray();

    return new Tuple(size[0], size[1], inputFile.Metadata.Duration.Ticks);
}
