Description Craig Minihan 2014-12-10 17:27:31 UTC
The System.Net.Sockets.Socket.Disconnect(bool reuseSocket) method delegates to Disconnect_internal() which is mapped to ves_icall_System_Net_Sockets_Socket_Disconnect_internal() in socket-io.c.

This function takes the MonoBoolean reuse parameter but does not use it. The DisconnectEx and TransmitFileEx are always invoked with the TF_REUSE_SOCKET flag which suggests that when reuse is false the socket will be reused anyway.

I noticed this problem when investigating a socket related issue which now looks like an application problem. So I do not know if the is genuinely a defect at this point, however the LOGDEBUG message in the function suggests that the reuse parameter is significant.
