Your LoadFrom loaded the assembly into the "LoadFrom binding context". When
the object is received over remoting, the remoting infrastructure does the
equivalent of Assembly.Load("AssemblyName"), which only searches the "Load
binding context". The two binding contexts are kept isolated intentionally
as described in the article Keith mentioned
(http://www.gotdotnet.com/team/clr/LoadFromIsolation.aspx).
I'm not sure if its always the best approach, but I have found it necessary
to sometimes circumvent this isolation by using my own assembly resolver.
I.e. hook the AppDomain.AssemblyResolve event to return a reference to the
assembly loaded into the LoadFrom binding context when necessary.
