Any object outside the application domain of the caller application should be considered as Remote Object. A Remote Object that should be derived from MarshalByRefObject Class. Any object can be changed into a Remote Object by deriving it from MarshalByRefObject . Objects without inheriting from MarshalByRefObject are called Non-remotable Objects.
The following example creating a Remote Object in VB.Net, RemoteTime , which send the current time to the Client Application using Remoting Framework. The RemoteTime class is derived from MarshalByRefObject and inside the class it has a method getTime() which return the current time from Remote Object.
Imports System
Public Class RemoteTime
Inherits MarshalByRefObject
Private currentTime As String = ""
Public Function getTime() As String
currentTime = DateTime.Now.ToShortTimeString()
Return "Remote Server Time : " & currentTime
End Function
End Class
