Hi,
Updating Collections package from 0.15.0-preview21 to Version 1.0.0-pre.3 breaks compilation with:
Library\PackageCache\com.unity.jobs@0.8.0-preview.23\Unity.Jobs\IJobParallelForDefer.cs(77,85): error CS8377: The type ‘U’ must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter ‘T’ in the generic type or method ‘NativeList’
I have same error, switched to Collections 0.17.0-preview.18 to fix it
Fixed in 1.0.0-pre.5
It happens again in 1.10
