I'm getting the following error

An unhandled exception of type
'System.Runtime.Serialization.SerializationException' occurred in
mscorlib.dll

Additional information: Cannot find the assembly SCQueueClientTest,
Version=1.0.2074.15411, Culture=neutral, PublicKeyToken=null.

...when I attempt to add an event handler delegate to a remoted object
called as follows:

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
        o =
Activator.GetObject(GetType(SCMessagingSingleton.SCMessageStore),
"tcp://localhost:64738/SCMessaging.rem")
        AddHandler o.TestEvent, AddressOf o_TestEvent
        o.TestFunction()
        RemoveHandler o.TestEvent, AddressOf o_TestEvent
    End Sub

    Private Sub o_TestEvent(ByVal sender As Object, ByVal e As
SCMessagingSingleton.SCMessageStoreEventArgs)
        MessageBox.Show(e.Message)
    End Sub

Without the AddHandler call, o.TestFunction() works perfectly.

Can anyone shed some light on this, bearing in mind that
"SCQueueClientTest" is the name of both the solution and the project for
this client, but is not explicitly declared in the project?

Setup code for the server is:
        Dim sp As New BinaryServerFormatterSinkProvider
        Dim cp As New BinaryClientFormatterSinkProvider
        Dim Properties As IDictionary = New Hashtable
        Dim channel As TcpChannel
        sp.TypeFilterLevel =
Runtime.Serialization.Formatters.TypeFilterLevel.Full
        Properties("port") = 64738

        channel = New TcpChannel(Properties, cp, sp)
        ChannelServices.RegisterChannel(channel)

        RemotingConfiguration.RegisterWellKnownServiceType( _
                    GetType(SCMessagingSingleton.SCMessageStore), _
                    "SCMessaging.rem", _
                    WellKnownObjectMode.Singleton)

And for the client:

        Dim ServerProvider As New BinaryServerFormatterSinkProvider
        Dim ClientProvider As New BinaryClientFormatterSinkProvider
        Dim Properties As IDictionary = New Hashtable
        Dim Channel As TcpChannel
        Dim RemoteType As WellKnownClientTypeEntry

        ServerProvider.TypeFilterLevel =
Runtime.Serialization.Formatters.TypeFilterLevel.Full
        Properties("port") = 0
        Channel = New TcpChannel(Properties, ClientProvider,
ServerProvider)
        ChannelServices.RegisterChannel(Channel)
        RemoteType = New
WellKnownClientTypeEntry(GetType(SCMessagingSingleton.SCMessageStore), _
                    "tcp://localhost:64738/SCMessaging.rem")
        RemotingConfiguration.RegisterWellKnownClientType(RemoteType)
