Tested this on an empty project with 2018.1b12 (the custom build), 2018.2b1 and 2018.2b2. After I added an assembly definition file, “Unity.Entities” could not be resolved anymore.
I vaguely remember someone else commenting on this as well. I’m posting this in case Unity is still not aware of this.

Which .NET Subset is used there?
.Net 4.x
Isn’t it one of the requirements for using ECS?
I had to manually add “Unity.Entities” to my asmdef file through a text editor rather than in editor. It is so far working for me, but not sure about any side effects yet
Nice, that’s good to know! I didn’t even think about trying that way.
