Get the duration of video in asp.net mvc

Question

I needed the duration of video from physical path.

The code that I have tried is:

using WMPLib;
WindowsMediaPlayer wmp = new WindowsMediaPlayerClass();
IWMPMedia mediaInfo = wmp.newMedia(Server.MapPath("~/Uploads/test.mp4"));
double duration = mediaInfo.duration;

But I am getting following error:

The type 'WMPLib.WindowsMediaPlayerClass' has no constructors defined Interop type 'WMPLib.WindowsMediaPlayerClass' cannot be embedded.
