Type.InvokeMethod not working in remote server object.

P: n/a
I just started using .NET Remoting.
I have a test system (client) which connects to our device (server)
running XP Embedded.

When my server object is called it uses a library where reflection
(Type.InvokeMethod) is used to dynamically invoke a "command-object" in a
The list of objects are created when server is started (in UI-thread).
Each entry in the command list stores a Type reference, an object reference
and the method name.
The command is invoked like this:

BindingFlags.Public | BindingFlags.NonPublic |
BindingFlags.Instance | BindingFlags.InvokeMethod,
null, commands[i].ObjectInstance, pars );

When I call this code from the UI-thread (when pressing a button in user
interface) it works fine, but when called from the server object I get a
MissingMethodException from InvokeMember.

Could it be something about permissions? (which I know next-to-nothing about).

Any ideas?

My remoting code is listed below.

--------------- THE CLIENT ( LibC.dll) ---------------

class TestConnectionRemoting : MarshalByRefObject, ITestOutput, IEventOutput
AccessorBase m_Accessor = null;

public override bool Connect()
WellKnownClientTypeEntry typeentry =
new WellKnownClientTypeEntry( typeof( AccessorBase ),
"tcp://localhost:399/testinterface" );
typeentry.ApplicationUrl = "tcp://localhost:399/testinterface";
RemotingConfiguration.RegisterWellKnownClientType( typeentry );

BinaryClientFormatterSinkProvider sinkprovider =
new BinaryClientFormatterSinkProvider();
IDictionary properties = new Hashtable();
properties["name"] = "TcpBinary";
properties["port"] = 0;

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

new TcpChannel( properties, sinkprovider, provider ), false );

m_Accessor = new AccessorBase();

// deliver event-output interface reference
m_Accessor.SetEventOutputInterface( (IEventOutput) this );

// call remote method where output will be sent back through
// the ITestOutput interface.
m_Accessor.ExecuteCommand( (ITestOutput) this, "login developer" );

return true;
