ViewState validation problem with dynamic types

I get the below error in my web application when ViewState contains
serialized objects of a dynamic type.

I have a dynamic assembly (not saved to a physical file) named
"ImplementorFactoryAssembly" that serves dynamically-created interface
implementors, simple classes with properties.

What bugs me is that deserialization works just fine; TypeHandle is stable
across postbacks, casting back to objects from ViewState works... this
exception is thrown after Load be before PreRender. It looks like there is
some page-level validation that requires all types in ViewState to be backed
by physical files. Not sure how to fix this.

Actually never mind, I backed up to make sure serialization was working as
expected and it wasn't. This isn't an ASP.NET issue.
