Problem with Dynamic class loading.

[Parag Joshi]

hi,
I am facing a wierd problem with dyanamic class loading.
I have a namespace called ETS.DAO which contains my
Data Access Object classes. All these classes implement a
common interface which is also in the same namespace.
I have a namespace ETS.Controller which contain my
comtroller classes.
My Web client instantiates the controller who in turn
fires appropriate methods on the DAOs.
In the controller i am using dynamic class loading to
load DAOs. The loading is happening fine. But the
Assembly.CreateInstance() returns an object. When I try to
typecast this object into the interface type i get an
error "Invalid cast".

The same code is working find when i use a windows forms
client.

Could somebody please tell me if I am missing something.

thanks in advance
