    Hi,

    I saw the DOTS Editor package recently got updated to be compatible with Entities 0.10, so I just tried adding it to a small DOTS sample project of mine. However, upon adding the package to my project, I get several errors that all look like this: 
    Library\PackageCache\com.unity.dots.editor@0.6.0-preview\Editor\EntityHierachy\DataDiffers\SharedComponentDataDiffer.cs(195,51): error CS0019: Operator '+' cannot be applied to operands of type 'Chunk.<Buffer>e__FixedBuffer' and 'int'


    I'm using Unity 2020.1.0b8, and Entities 0.10.0-preview. I'm not sure if this is happening due to some incompatibility in my setup, or if this is a bug with the Editor package.

    Hi,

    Which `API Compatibility Level` are you using ? (Edit > Project Settings > Player > Other Settings)

    If you're using .NET 4.x try to switch to .NET Standard 2.0 and reimport the DOTS Editor package (Project window > Packages > right click on `DOTS Editor` directory > reimport).
    This should fix these compilation errors.

    I just had to restart the editor...

    "it is because it uses a new version of Burst, which requires to restart the editor to work (only once after the library is created)"

    restarting worked for me as well, without having to lower .NET to 2.0

    I was having this problem too, though restarting didn't work. Removing the library folder didn't work either.

    What worked for me, was updating from Unity 2020.1b14 to 2020.1b15.

    For anyone running into this - make sure the whole DOTS suite is updated since the packages all ship in lockstep. In my case, I had forgotten to upgrade unity.physics to latest.

    There is no .NET 4.x or .NET Standard 2.0

    Only have .NET Framework and .NET Standard 2.0
