Hello! Please let me know if there is any public bugtracker for virtuoso. As I didn't find it, I'll post the following information here.
I had problems connecting to Virtuoso using ADO.NET provider. IPV6 disabling resolved this problem. It is okay for developer machine, but such a solution won't be suitable for our customers :) I have found the following code using Reflector at virtado3.dll library's TcpConnection.Open method: Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); This blogpost ( http://blogs.msdn.com/wndp/archive/2006/10/24/creating-ip-agnostic-applications-part-2-dual-mode-sockets.aspx) tells how to make sockets work with both IPv4 and IPv6 (shortly, we just need to create IPv6 socket and disable IPV6_V6Only option). Regards, Alexander
