Re: [Mono-dev] Cross-Appdomain remoting
Ah! The idea of changing the lifetime was enough info for me to find the cause. Hm, I could swear I saw a difference in behavior between .NET and Mono, but my simplified test case revealed an identical error (with slightly different text) in .NET - that led me to InitializeLifetimeService. I overrode InitializeLifetimeService on the MarshalByRef objects and returned null - this prevents the objects from expiring. Thanks for the reply! - Kipp On Thu, May 5, 2011 at 4:49 PM, Robert Jordan robe...@gmx.net wrote: Hi, On 05.05.2011 22:11, Michael Mudge wrote: I'm seeing strange behavior on our device - AppDomain A has launched AppDomain B, and wired the DomainUnloaded event.
