Creating and using multiple dlls in a project

[thiago777]

Hello,

I have some questions concerning the use of multiple dlls in a project, for example:

First I must create a dll A which uses dll from project Z.
Then someone else wants to use my dll A, but also functions from dll Z.

Z is an open-source dll which have updates from the original author constantly, therefore this would not be the right thing to provide my A dll a new compile every time dll Z gets an update.

If we include both dll A and the new dll Z (updated) in a project we have assemblies conflicts.

What is the most correct way of re-using the same dll in a project then?

thanks in advance,
Thiago.
