Failed to create EntityStore in runtime compiled code

[inmny]

I tried to use your framework(netstandard 2.1) in a unity mod. The mod is compiled and loaded at runtime.

The mod is compiled with "allow unsafe code" on Windows.

Framework version:

• 3.0.0-preview.13
• 3.0.0-preview.10
• 2.2.0

Dependencies version:

• Friflo.Json.Burst 1.0.2
• Friflo.Json.Fliox 1.0.2
• Friflo.Json.Fliox.Annotation 1.0.2
• System.Runtime.CompilerServices.Unsafe 5.0.2/6.0.0

Log:

[Error  : Unity Log] [NML]: The type initializer for 'Static' threw an exception.

Code:

using Friflo.Engine.ECS;
using NeoModLoader.api;
using UnityEngine;

namespace Cultiway
{
    internal class ModClass : BasicMod<ModClass>
    {
        protected override void OnModLoad()
        {
            var world = new EntityStore();
            world.CreateEntity<Velocity>(new Velocity() { val = new(1, 1, 1) });
        }
    }

    struct Velocity : IComponent
    {
        public Vector3 val;
    }
}

What should I do for more detailed information?

To get more info about the TypeInitializationException add a try / catch and log its InnerException property.
The log should contain the exception class Name, the Message and StackTrace.
In case its InnerException is not null it should also be logged.

Log code:

LogInfo($"{Type.GetType("UnityEngine.Application, UnityEngine")}");
try
{
    _ = new EntityStore();
}
catch (Exception e)
{
    do
    {
        LogInfo($"Name: {e.GetType().Name}\nMessage: {e.Message}\nStackTrack: {e.StackTrace}");
        e = e.InnerException;
    } while (e != null);
}

It seems that it is running on NativeAOT. But I am sure that it is in unity runtime.

I find its problem: It tries to load "RuntimeFeature" type which is only provided by "System.Runtime" when call SchemaUtils.RegisterComponentTypesByReflection no matter whether it is used.
