Windows Service

Hi all,
I have a Remoting application that using http channel.
When I tried to make Windows Service from this application all seems to be
all right until I restart service. I have the following Exception.

Service cannot be started. System.Net.Sockets.SocketException: Only one
usage of each socket address (protocol/network address/port) is normally
permitted
at
System.Runtime.Remoting.Channels.Http.HttpServerChannel.StartListening(Objec
t data)
at System.Runtime.Remoting.Channels.Http.HttpServerChannel.SetupChannel()
at System.Runtime.Remoting.Channels.Http.HttpServerChannel..ctor(String
name, Int32 port, IServerChannelSinkProvider sinkProvider)

Service OnStop method is:
_httpChannel.StopListening(null);
ChannelServices.UnregisterChannel(_httpChannel);
_httpChannel = null;
GC.Collect();
GC.WaitForPendingFinalizers();

But it doesn't help. I must wait around 20 seconds before start service
again.
Is there a way to stop HttpServerChannel's socked immediately, because
otherwise I can't restart my service.

Thanks in advance.

Are you doing any threading in your application? You might want to try
AppDomain.Unload:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemappdomainclassunloa...

You could also create a child AppDomain at startup to actually run your
logic and with the OnStop method you could perform an Unload on that
AppDomain:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconprogrammingwithapplicationd...

This would allow you to truly isolate your code and be able to control
stopping it completely.

Thanks,

Sam

did you make sure you did:

RemotingServices.Disconnect(obj)

on the MarshalByObjectRef that you're serving up on that channel before you
unregister the channel (if you used RemotingServices.Marshal(obj, URI))?
