Can't find Unity Collections Package?

Hello

Thanks to an error caused by a new asset, I'm had to reset my packages.

I received a bunch of error messages in the console, all of which I've resolved by reimporting relevant packages from the package manager.

The 1 remaining error is :

Assets\assets (bought)\Digger\Sources\Digger\Jobs\VoxelModificationJob.cs(35,28): error CS0246: The type or namespace name 'NativeQueue<>' could not be found (are you missing a using directive or an assembly reference?)

I think to resolve this I need to add the 'Unity Collections Package', but it isn't in the package manager.

Has the package with NativeQueue been renamed? Is there another way I can add Unity Collections Package?

What can I do?

 

Thank you!

 

It's not available in the preview packages anymore in the most recent version of the package manager, where can i get this nowadays?

Additionally, make sure you use these package addresses by adding packages using git URL.

Took me a minute.

 

I installed the Jobs package and Collections seemed to appear in my packages along with it once I did that.

 

I added this package by name (It didn't appear in a list when I searched, preview packages were checked). Just typed com.unity.collections, waited for a couple of minutes and it worked
