Unable to generate DOTS C# solution

Hi all,

First, thank you for the Project Tiny feature, it sounds promising

I am trying actually to perform some debugging on my small game and i have read in the "Get started" document ( https://docs.google.com/document/d/...HfnAX-CpYLK3aOdwA/edit#heading=h.flt05qfyo528 ) that i can attach the process to visual studio debugger through a special DOTS C# solution. It is cool.

But unfortunately, i am not able to generate this solution using the "Generate DOTS C# solution" menu entry, i get the following error :

Generate DOTS C# Solution failed.

I am using Project Tiny 0.29 preview with Unity 2020.1.4f1.
It seems mscorlib is not found, so i assume i miss one assembly definition reference in my assembly definition asset :

{

    "name": "GameSystems",

    "references": [

        "Unity.Entities",

        "Unity.Jobs",

        "Unity.Burst",

        "Unity.Mathematics",

        "Unity.Transforms",

        "Unity.Collections",

        "Unity.Physics",

        "Unity.Tiny.Input",

        "Unity.Tiny.RendererExtras",

        "Unity.Tiny.Core",

        "Unity.Tiny.Rendering",

        "Unity.Tiny.Audio",

        "Unity.Tiny.Text",

        "Unity.Tiny.Animation",

        "Unity.Tiny.Particles",

        "Unity.Entities.Runtime",

        "Unity.Scenes",

        ""

    ],

    "includePlatforms": [],

    "excludePlatforms": [],

    "allowUnsafeCode": false,

    "overrideReferences": false,

    "precompiledReferences": [

        ""

    ],

    "autoReferenced": true,

    "defineConstraints": [],

    "versionDefines": [],

    "noEngineReferences": false

}

But i am not able to find out which one is missing.
I looked to the TinyRacing example, there is the same issue, cannot generate the DOTS C# solution.
I also tried to only check Windows .NET 2.0 target with Debug / Develop configuration, but no more success.

Any idea ?

Thanks beforehand

 

Hi Abdul,

Good catch, i was missing .NET Framework 4.6.1 SDK.
It is working good with 4.6.1, thank you !
