Hi,

Thanks again! The references for the primitives are very useful, they
cover most of what I need.

I still don't fully understand the correct way to read modules and
type definitions, though (my apologies). Do I need to use
ModuleDefinition.ReadModule to do this? The types I need (such as
PropertyChangedEventHandler) all reside in system.dll and
mscorlib.dll.

In the example below, is theDefinition a TypeDefinition? Is this
something I get from the module I read, or something I create myself
and pass to myModule.Import?

I'm sorry for these basic and naive questions, hopefully my
understanding will improve soon!

Kind regards,
Einar
