“Object has been disconnected or does not exist at the server” exception

Question

I need to use cross-appdomain calls in my app, and sometimes I have this RemotingException:

Object \'/2fa53226_da41_42ba_b185_ec7d9c454712/ygiw+xfegmk

Answer 1

This question has been answered in great detail already on StackOverflow. TL/DR:

1. If you want Singleton semantics override InitializeLifetimeService to return null
2. Use ClientSponsor to keep you object alive longer.
