You can only look through assemblies to find all subclasses - if you
don't know all the assemblies that might contain subclasses, you can't
find them.

With that restriction, you can use Assembly.GetTypes, and then go
through each type and use Type.IsAssignableFrom to find out if the type
is derived (directly or indirectly) from your base type.
