Add managed dll to an Assembly Definition

Hello,

I have downloaded the Moq library and its dependencies for testing, and I would like to add all of these dlls to an Assembly Definition.
Is this possible?

I know you can do this with scripts, if the scripts are in the same folder, the will be in that assembly, but I don't know if something like that could be done with dll's

Thank you

 

I was doing that, but the plugins remained referenced in the main assemby.

I was missing to uncheck "Auto Reference" in the dlls

Thank you!
