    Has anyone else had this error when upgrading to preview 26?

    Library\PackageCache\com.unity.entities@0.0.12-preview.26\Unity.Mathematics.Extensions\MinMaxAABB.cs(27,52): error CS0246: The type or namespace name 'AABB' could not be found (are you missing a using directive or an assembly reference?)

    I'm not having the issue but I'm running the mathematics library version 1.0.0-preview.1

    The entities package only depends on 0.0.12-preview.20 so maybe they've buggered the dependency version again, try upgrading mathematics.

    I noticed that and upgraded. Still getting the same error. Maybe it's a cache problem. I'll try removing and reinstalling entities p26.

    Edit: Nope that didn't do it.

    what version of unity?

    I also did a full cache clear (deleted Library folder) when I upgraded because I was getting some random errors. Good last resort.

    I'll try that.

    I'm on 2019.1.0b1

    I tried upgrading to 2019.1.0b5, but got that error plus more errors so I downgraded.

    I am getting the same error. I uninstalled entities and mathmatics, deleted Library folder. Reinstalled. Still same error.

    Deleting the library Folder didn't work.

    But I made a new project and it worked. I replaced the dependencies in my original project's manifest.json with the dependencies from the new project's manifest file and it's working.

    The only difference I can see is that Unity.Mathematics isn't explicitly listed in the manifest now.

    I found the answer and it's a little weird:

    1. 
    AABB
    is a struct that is defined from the Unity Entities package (Scripting API here).
    2. However, it's written into the 
    Unity.Mathematics
    namespace.
    3. If you use 
    .asmdef
    files like I do, we have to reference the 
    Unity.Mathematics.Extensions
    assembly.

    Hi,

    I upgraded a project to 2019 and have this issue, seems i cant get a correct emtnties and math combination.

    Is there any easy way to not destroy my project and just make it work ?
