collection.17 upgrade broken

After upgrade to collection.17 entities package broken ..
I mentioned that public struct Words was [Obsolete],
but entities package can't find it any way...

 

What version of editor?

 

I have personally experienced this issue in 2020.3.8f1 and 2020.3.9f1

 

You meant words or worlds?

 

Also got this error. I guess Entities pkg is just not ready to work with this Collections update.

 

Remove library folder, it should help. Warning: it will reimport your project.

 

That's terrible for our 1TB project...I tried remove assembly caches and package caches but it dose not work.

 

No it is not. It may actually help, as there may be some corrupted files after packages update
Basically after clearing library folder, Unity forces to load all library again a fresh.

 

P

OMG, I tested with blank project and I'm failed... I'm going to submit a bug report

 

On Discord some are speculating it's for the new entities release.
Why not just downgrade for the time being? It's clearly not worth the hassle.

 

Downgrade solved the problem for me

 

What to do if the downgrade is broken as well? Tried already to delete manifest.json and object and library and started to re-add packages one by one them but it still does trigger this bug oO. Where does unity even take the version from if the manifest.json and package-lock.json are deleted?

After every downgrade click it does pretend to do some work, but nothing changes.

Edit: Fixed. I had to repeat it, there are just not many combination of Dots packages that are compatible and that simply made it a boring tedious task to start at a very old version and trying out all combinations until there was one error less and to repeat the cycle. Not making the packages visible in the package manager made this a particular fun...

 

I think we should take this as reference:
Unity - DOTS Releases - Latest Release: DOTS 0.17 - Unity Forum

 

you could just ask me. collections 0.17 is broken but 0.15 is fine

 

Any update on this? The most recent release of the com.unity.collections package (0.17.0-preview.16) is incompatible with the latest version of the com.unity.entities package (0.17.0-preview.21).

As others have mentioned, using these packages together results in the following error message when compiling com.unity.entities:

Library\PackageCache\com.unity.entities@0.17.0-preview.42\Unity.Scenes\ResolveSceneReferenceSystem.cs(34,16): error CS0246: The type or namespace name 'Words' could not be found (are you missing a using directive or an assembly reference?)​

For now, this can be avoided by sticking to an older com.unity.collections package (version 0.15.0-preview.21), but it seems odd that this incompatibility is still unresolved over a week after release. Anyone attempting to use the latest versions of the DOTS packages is going to run into this.

 

using 2020.3.11f1 (LTS)
I'm seeing this error with Collections Version 0.17.0-preview.18 and Entities Version 0.17.0-preview.42

Library/PackageCache/com.unity.entities@0.17.0-preview.42/Unity.Scenes/ResolveSceneReferenceSystem.cs(34,16): error CS0246: The type or namespace name 'Words' could not be found (are you missing a using directive or an assembly reference?)
