title: Is there a UPnP Library for .NET (C# or VB.NET)?
body: <p>I'm working on a P2P application, and I need to get it to communicate through NAT Routers / Firewalls using UPnP. However, it doesn't seem that the .NET Framework includes support for UPnP.</p>
  
  <p>Is there a UPnP Library for .NET? C# or VB.NET?</p>
  
  <p>UPDATE: I have since found the NATUPnP 1.0 Type Library (NATUPNP.DLL) COM Component that is part of Windows (since Windows XP) that allows you to easily setup/maintain Port Forwarding using UPnP.</p>
  
  <p>I wrote an article with code samples here:
