Object returned by proxy method must also be a proxy

[sancheolz]

Describe the bug When a proxy returns an object returned by its method, this object must also be a proxy. Classic remoting behaves like this

To Reproduce Steps to reproduce the behavior:

• For shared use this code or attached solution RemotingTestL.zip

namespace HelloWorld.Shared
{
    public interface ISayHelloService
    {
        ISubTypeHelloService NewSubTypeHelloService(string name);
    }

    public interface ISubTypeHelloService
    {
        string GetName();
    }
}

• use this code for implementation

public class SayHelloService : MarshalByRefObject, ISayHelloService
    {
        /// <inheritdoc />
        public ISubTypeHelloService NewSubTypeHelloService(string name)
        {
            return new SubTypeHelloService(name);
        }
    }

    [Serializable]
    public class SubTypeHelloService : MarshalByRefObject, ISubTypeHelloService
    {
        private string _name;
        public SubTypeHelloService(string name)
        {
            _name = name;
        }

        /// <inheritdoc />
        public string GetName()
        {
            return _name;
        }
    }

• And this code for client

var client = new RemotingClient(new ClientConfig
                {
                    ServerHostName = "localhost",
                    ServerPort = port,
                    Serializer = new BinarySerializerAdapter()
                });

                client.Connect();

                // Create a proxy of the remote service, which behaves almost like a regular local object
                var proxy = client.CreateProxy<ISayHelloService>();
                var subtype = proxy.NewSubTypeHelloService("mySubType");
                Debug.Assert(CoreRemoting.ClassicRemotingApi.RemotingServices.IsTransparentProxy(subtype));
                var subtypeName = subtype.GetName();

• For Server use code from example
• Run Server and Client
• Exception System.Runtime.Serialization.SerializationException is thrown.

System.Runtime.Serialization.SerializationException: Не удалось найти сборку "HelloWorld.Server, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null". в System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembly() в System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAssemblyInfo assemblyInfo, String name) в System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) в System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryObjectWithMapTyped record) в System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryHeaderEnum binaryHeaderEnum) в System.Runtime.Serialization.Formatters.Binary.__BinaryParser.Run() в System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(HeaderHandler handler, __BinaryParser serParser, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) в System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream, HeaderHandler handler, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) в CoreRemoting.Serialization.Binary.BinaryFormatterExtensions.DeserializeSafe(BinaryFormatter formatter, Byte[] rawData) в CoreRemoting.Serialization.Binary.BinarySerializerAdapter.Deserialize[T](Byte[] rawData) в CoreRemoting.RemotingClient.ProcessRpcResultMessage(WireMessage message)

Expected behavior The type of subtype must be Castle.Proxies.ISubTypeHelloServiceProxy

Additional notes When I copy HelloWorld.Server.exe to client dir the type of subtype will be HelloWorld.Server.SubTypeHelloService. With classic Remoting proxy and subtype will be System.Runtime.Remoting.Proxies.__TransparentProxy both.
