I have a signed assembly which has say version 1.0.0.0 it has serializable
objects in it, say I serialize an object to a database... ok the object
stores the schema for version 1.0.0.0... now we are at version 1.5.0.0 and
the object's schema has not changed, and I can gurantee this... but when you
try to deserialize the 1.0.0.0 object it says "Parse Error, no assembly
associated with Xml key" because the versions do not match... how do I get
the version 1.5.0.0 to deserialize version 1.0.0.0 objects when I can
gurantee they have not changed in schema.. thanks!

I am not sure about XML serialization, but .NET 2.0 introduced version
Version Tolerant Serialization (VTS) for both binary and SOAP formatting.

I can't seem to get SOAP objects that are made with the soapformater and
serialized to xml to work in a VTS scenerio... always throws an error saying
wrong version... (this is .NET 2.0 SP1 here)
