Namespace:  System.Runtime.Remoting.Messaging
Assembly:  mscorlib (in mscorlib.dll)

public class ReturnMessage : IMethodReturnMessage, 
	IMethodMessage, IMessage


This class makes a link demand and an inheritance demand at the class level. A SecurityException is thrown when either the immediate caller or the derived class does not have infrastructure permission. For details about security demands, see Link Demands and Inheritance Demands.
