this namespace or type £¿£¿

Namespace RemotingSamples
Public Class Sample
Shared Sub Main
Dim chan As TCPChannel -> error! IDE report not defined type!!
chan = New TCPChannel(8085 )
ChannelServices .RegisterChanne l(chan)
RemotingConfigu ration.Register WellKnownServic eType( _
Type.GetType("R emotingSamples. HelloServer, object"), _
"SayHello", WellKnownObject Mode.SingleCall )
System.Console. WriteLine("Hit to exit...")
System.Console. ReadLine()
End Sub
End Class
End Namespace
