can't compile package

[Aegel5]

Library\PackageCache\com.akb.knn@e5efc63\Demo\KnnVisualizationDemo.cs(7,32): error CS0234: The type or namespace name 'ParticleSystemJobs' does not exist in the namespace 'UnityEngine.Experimental' (are you missing an assembly reference?)

[sambeebe]

same issue, did you manage to solve this?

[skymeson]

Same issue here. Is there a version of Burst package we should be using? 0

// After particle job

I really need this but I have no idea how to apply this. I googled how to do diff patches in github but no luck, it's all .py patch based
