.NET Remoting: Passing through the obstacles path from version 1.0 to 1.1

Houston, we have a problem. One small step for mankind, one Giant irritation for developers.


The following article's aim is to help those of you who want to use .NET Remoting on Framework 1.1*. This article will not teach you Remoting, mainly because I am not an expert on that field. Furthermore, my CodeProject colleagues published some useful and nice to read articles on that issue (see links below). The attached projects were kept simple as possible to allow you to overcome the changes presented by Framework 1.1*. It handles the maladies of security exception, serialization and delegates issues.


Recently, I have faced the challenge of exposing objects via .NET Remoting. Like the most of you, I have started with the MSDN, and of course CodeProject, but all the examples were suited for Framework 1.0 only. Attempts to run 1.0 project on a 1.1 Framework ends with lots of exceptions.

  • Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level.
  • Because of security restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed.
  • 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.

The web is full of developers' complaints on the very same problems but I have not found a simple, corrective and comprehensive example. So there you have it!.

Code snippets

Activate through Config files

Server side configuration

    <application name="ServerAssembly" >
          <!-- type: is the full type name 
(type the class that inherit from MBR,assembly) of the 
          <!-- objectUri - alias -->
          <!-- Server tells remoting Here's a type 
Here's how and when to instantiate the type
Here's the name (end point) a client will use to contact the type
        <wellknown mode="Singleton" 
            type="SharedAssembly.SharedObj, SharedAssembly" 

objectUri="ParachuteExample" />
            <channel ref="tcp" port="6123">    
                    <formatter ref="binary" typeFilterLevel="Full" />

Server side code

RemotingConfiguration.Configure ("ServerAssembly.exe.config");

Client side configuration

               type="SharedAssembly.SharedObj, SharedAssembly"
    <channel ref="tcp" port="0">        
      <formatter ref="binary" />
      <formatter ref="binary" typeFilterLevel="Full" />


Client side code

RemotingConfiguration.Configure ("ClientAssembly.exe.config");
SharedObj remObject = new SharedObj();

Activate through code

Server side

    BinaryClientFormatterSinkProvider clientProvider = null;
    BinaryServerFormatterSinkProvider serverProvider = 
       new BinaryServerFormatterSinkProvider();
    serverProvider.TypeFilterLevel = 

    IDictionary props = new Hashtable();
    props["port"] = 6123;
    props["typeFilterLevel"] = TypeFilterLevel.Full;
    TcpChannel chan = new TcpChannel(



Client Side

    BinaryClientFormatterSinkProvider clientProvider = 
       new BinaryClientFormatterSinkProvider();
    BinaryServerFormatterSinkProvider serverProvider = 
       new BinaryServerFormatterSinkProvider();
    serverProvider.TypeFilterLevel = 

    IDictionary props = new Hashtable();
    props["port"] = 0;
    string s = System.Guid.NewGuid().ToString();
    props["name"] = s;
    props["typeFilterLevel"] = TypeFilterLevel.Full;
    TcpChannel chan = new TcpChannel(


    Type typeofRI = typeof(IParachute);
    IParachute remObject = (IParachute)Activator.GetObject(    typeofRI,

Using the code

Since some of you like configuration files while others like to connect and create the well known object via code, I have included two projects accordingly. Both projects, and, include the same assemblies as follows:

  • ClientAssembly
  • ServerAssembly
  • SharedAssembly

GeneralExample fails using HttpChannel Pinmemberrcarsten14-Nov-06 22:13 
Hi everyone,
i have discovered a strange problem. Probably someone can help me or give me a hint how to solve this problem. I just tool the depicted example and converted it to use VS2005 with .Net 2.0 .
Everything worked fine so far. Next it experimented a lil bit and replaced the TcpChannels by HttpChannels, nothing else.
With this little modification the remote callback doesnt work anymore. The client is able to successfully call the remote methods of the server but then the program hangs. there is no callback to the passed eventwrapper.
Anyone an idea what the cause of this problem may be?
Kind regards
