.NET Remoting

[Sharon]

I’m trying to build a generic Publisher-Subscriber that will work over the
net, so I’m using the Remoting.
I wish that the subscriber user will be notify about the messages sent by
the remote publisher, so I used delegate that the user will be able to set on
it his own function and to be notify by it ob any publisher message.
The trouble is that this delegate must not be static because there may be
many subscribers, and each subscriber may have different function hooking on
that delegate.
But if I don’t set this delegate to static I get an exception:

“An unhandled exception of type 'System.Security.SecurityException' occurred
in mscorlib.dll
Additional information: Type System.DelegateSerializationHolder and the
types derived from it (such as System.DelegateSerializationHolder) are not
permitted to be deserialized at this security level.�

How can I fix it???
