Can't add references to Assembly Definition Files

Hi guys!

I'm using Unity 2018.2.0f2

I wanted to structure my project a little bit and came across Assembly Definition Files. The problem is, that I can't add references. The selection-list only shows my own Assembly:



Any ideas? Thank you very much!

 

Is your code compiling? Is there any code under the other assembly definition?

 

Yes, my code compiles (without the use of the Assembly Definition).
What exactly do mean with "Is there any code under the other assembly definition"?

Here's the rough structure of my project:

• [Other Assets]
• [Game Scripts]
• [Editor (Scripts)]
• [Testing]
  • [Editor (Scripts)]
    • Assembly Definition

There are no other Assembly Definitions than the one in Testing/Editor.

 

You can only add references to other assembly definition files through the menu. You can add references to official packages imported through the package manager, but that has to be done manually (for now).

What are you trying to add references to?

 

I see - this was a misunderstanding. I saw a video where the instructor added package manager references somehow.
When will that be possible?
