If the target object already inherits from the abstract base class MarshalByRefObject, the necessary features are automatically available. The following code shows a simple object that inherits from MarshalByRefObject and exposes a single method and a single property.

public class OrderTransactions : MarshalByRefObject
{
  private string greeting;

  public int CountOrderItems(string customerName)
  {
    int orderCount = 0;
    // Code here to get count of number of orders from database.
    // ...
    return orderCount;
  }

  public string InvoiceGreeting
  {
    get { return greeting; }
    set { greeting = value; }
  }

}
