How to group Interface Classes into dll

[fiona_conard]

Hi all,

I got 20 interface classes. Base on what criteria, how should i group them
into a dll? I do not want to put them all into one dll because if one class
need to break compatibility then the others are forced to break too.

Please advise. Thanks

Group them by common functionality - for example, place all your database i/o interfaces together.

Generally, if your interfaces are reasonably well abstracted (in other words if your interface is 'self-sustaining' and does not depend on the metods & properties found in another interface)you should have quite a few dll's if you expect to have to change things.

By the way - if you expect change just add interfaces like:
Implements IInterface
then later:
Implements IInterface2

When you change it add an interface do not change the old one:
Implements IInterface2 - add the new interface in same same dll as the old one.
