Compile error after upgrade of ECS to 0.0.12-preview.8

Hi,

I started getting this compile error after latest upgrade of com.unity.entities.


AppData/Local/Unity/cache/packages/staging-packages.unity.com/com.unity.entities@0.0.12-preview.8/Unity.Entities/SerializeUtility.cs(159,52): error CS1644: Feature `out variable declaration' cannot be used because it is not part of the C# 6.0 language specification

Any ideas ?

 

Weird, you need .net 4.6 to use entities therefore should have 6.0 support (well actually 7.0 support because it ships with incremental compiler)

 

Yeah, really weird. For now i've reverted incremental compiler and entities back to previous version

 

Ok. The problem was when i added incremental compiler as well as entities package.
After removing incremental compiler and keeping latest entities package it compiles correctly

 

Does it stay compiled correctly though? I had a similar temporary success by playing around with older versions and then going back to the latest, but then found after exiting the editor and going back in that it was all borked again.

 

i'm using latest entities package but I removed incremental compiler from the packages. Everything works, the only thing i i noticed is that burstcompiled job was giving me some runtime exception. It forced me to re-think the logic and split the job into two.

Other than that i also upgraded the unity to the latest via hub.
