C# – Issue with remoting when different domains are used

cremoting

I have the following project:
server, client, remote object. client does something, then pass the proxy of remote object to the server. All the things work property until server and client are in different domains. Now, when I try to pass result to server I have an exception

"An unhandled exception of type 'System.Runtime.Remoting.RemotingException' occurred in mscorlib.dll

Additional information: This remoting proxy has no channel sink which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server. "

some sources on Internet says that I need to create some additional channel but I don't know where and how should I do that because I have the channel registration on server and client yet.

Info:
server - domain 2
client - domain 1
remote object - domain 1

Thank you

Sounds like a permissions issue to me. How are you hosting your remoting objects? How are you authenticating across domains? Here's a decent article on some of the issues you might face with auth.

From this article ...

By default, a TCP client channel authenticates itself with the user identity under which the client process is running. You can specify an alternative identity by setting the domain, username, and password properties to specify an alternative identity

Have you specified correct credentials (including domain) on your channel properties?

C# – Passing remote object from one App Domain across to another process

I have seen this error message in a similar situation to yours when I was doing the following:

In the Service process, I had 2 app domains: A and B.

It is in AppDomain B that I setup the remoting channel, and created a remote object, RemotableObject, to the remote Process.

Then, I created an object, anObject, in AppDomain A, and called:

RemotableObject.PassProxyToOtherExe(anObject);

Now somewhere in the remote process, I am accessing a property of anObject (anObject.Name) and this is where the error occurs!

I believe this happens because .NET is trying to access the original object that you created in AppDomain A with the data that you are requesting, but, because there is no remoting channel to AppDomain A, the remoting channel was established between appdomain B and the remote process, the data cannot be grabbed.

To resolve this issue in my case, I created a factory in AppDomain B that would create the object that I wanted and passed a reference back to AppDomain A (anObject needs to inherit from MarshalByObjectRef anyway if you are passing across remoting) and it seems to have worked.
