Hi *

I'm trying to make this run:

FIX: Remoted Events (Chat) Sample in Framework Documentation Does Not Work
as Expected
http://support.microsoft.com/default.aspx?scid=kb;en-us;312114

But I'm getting this:

System.Security.SecurityException: Type System.DelegateSerializationHolder
and the types derived from it (such as System.DelegateSerializationHolder)
are not permitted to be deserialized at this security level.
