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 C#, 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 returns the current time from the Remote Object.

{ 
    private string currentTime = "";

Compile the class RemoteTime.cs into a library using the command-line tools that shiped with the Visual Studio SDK .

At the command prompt type the following command:

csc /t:library RemoteTime.cs

After you compile the RemoteTime.cs , you will get a file called RemoteTime.dll in the directory where your compiler resides.

If your file RemoteTime.cs is residing in c:\src then you should type command like the following :

csc /t:library c:\src\RemoteTime.cs
