Hi all,
I have a serious problem regarding the subscription to events to a
remote objects.

I have sometimes this error, and I really don't know why !

Does anybody can help me?

Thanks

Here is the error:
An unhandled exception of type
'System.Runtime.Serialization.SerializationException' occurred in
mscorlib.dll

Additional information: Serialization will not deserialize delegates
to non-public methods.

Here is the stack trace:
Unhandled Exception:

will not deserialize delegates to non-public methods.

Sounds like when you register your event handler that the callback method
you're using is a non-public method of the class (as it says in the error
message). When you register for a remote event you must use a public method
for the event handler.

Thanks for your help, but I finally found the solution, it's just a
question of [Serializable] tag at the beginning of my client class...
