Is it necessary to put the shared assembly in GAC only?

Question

I want to share a dll in between two projects.

Is it necessary to put the dll in GAC only or can I place it in any folder?

Answer 1

The assembly loader will look for the assembly in several places, one of which is the execution directory.

This means that you can simply copy to multiple directories.
