<p>I am looking for a way to interact with a standalone full version of Windows Media Player.<br>
Mostly I need to know the Path of the currently played track.</p>

<p>The iTunes SDK makes this really easy but unfortunately there really isn't any way to do it with Windows Media Player, at least not in .Net(C#) without any heavy use of pinvoke, which I am not really comfortable with.</p>

<p>Thanks</p>

<p>Just to clearify: I don't want to embedded a new instance of Windows Media Player in my app, but instead control/read the "real" full version of Windows Media Player, started seperatly by the user</p>

I had this

in my bookmarks but have NOT tested it in anyway. Just a pointer in the right direction. It's nothing official and will require a bit of digging, but you should get a fairly simple wrapper (which will still use PInvoke under the hood - but you won't see it) around Windows Media Player.
Hope that helps.
Oh, I misunderstood. I thought you were talking about controlling the currently running Windows Media Player instance. If you are hosting Windows Media Player yourself then WMPLib is certainly the better solution.
