Well, I got bored, and needed to write a working library for winamp in .NET, so I figured I'd release it here as well, and help some of you guys out.
It's in .NET 3.5, so you guys are pretty much S.O.L. if you're not programming in 3.5 (not sure why you wouldn't be already...).
It's fully CLS compliant, so you can use it from any .NET enabled language you choose. (Hence why I'm releasing it here, not the C# or VB sections)
It's a library of static classes, the main (and only exposed) being the WinampLib.Winamp class. There's lots of nifty little things in there, as well as some pretty useless, but included anyway, methods and members.
This library is compatible with all winamp versions 2.1x and newer. So there really shouldn't be a problem here at all. (Current is 5.0x)
If you think of anything you'd like me to add, feel free to post here and I'll get to it.
