Remoting and missing channel sinks

Question

I ran into a remoting exception:

\"This remoting proxy has no channel sink which means either the server has no registered server channels that are listening, or

Answer 1

To expand on @RonCohen's answer -

On the server, one typically creates a full channel the fun way (especially if you want to fix the TypeLevelFilter problem ala https://stackoverflow.com/a/9268223/344638):

BinaryServerFormatterSinkProvider serverProvider;
BinaryClientFormatterSinkProvider clientProvider;
Hashtable properties = new Hashtable();

serverProvider = new BinaryServerFormatterSinkProvider();
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;

clientProvider = new BinaryClientFormatterSinkProvider();

properties.Add( "port", 8080 );

this.chan = new TcpChannel( properties, clientProvider, serverProvider );

ChannelServices.RegisterChannel( this.chan, true );

Lets say you're using a sponsor on the client side. If you don't, and the client doesn't call the remoted object for a while, the server will drop the object:

Object '/70c96e17_02a8_4e1a_a040_7b671b4a66b4/3fssua+asfozgeqqkrjql+4k_1.rem' has been disconnected or does not exist at the server.

So you're using a sponsor, which the server then occasionally calls to renew the remoted object. But! Now the server has a remoted object - the sponsor gets remoted to the server side when the sponsor calls ILease.Register. But if the server doesn't have a remoting channel to the client, this fails.

So, in the same way that the server has to expose a remoting channel to the client for the client to access remoted objects, the client has to expose a remoting channel to the server for the server to be able to access remoted objects like sponsors. In the end, both my client and server side end up having the same channel construction code (above), except I use different port numbers on each side.
