Is Burst Not Support AddSharedComponent?

Hi all,
in ecs 0.51.0-preview.32,when use EntityCommandBuffer.ParallelWriter call AddSharedComponent,

in runtime console error:
Burst error BC1051: Invalid managed type found for the field `EqualFn` of the struct `Unity.Entities.FastEquality.TypeInfo`.: the type `System.Delegate` is a managed type and is not supported

Code (CSharp):

1. public struct TestShared : ISharedComponentData
2. {
3.         public int Value;
4. }

Code (CSharp):

1. private static void CreateIsoObject(EntityCommandBuffer.ParallelWriter ecb,
2.             int entityInQueryIndex, EntityArchetype archetype,
3.             int num, Entity prototype)
4. {
5.         var random = new Random(1);
6.         for (var i = 0; i < num; i++)
7.         {
8.             var entity = ecb.Instantiate(entityInQueryIndex, prototype);
9.  
10.             var x = random.NextFloat(0, 10).Fixed(0);
11.             var y = random.NextFloat(0, 10).Fixed(0);
12.             var d = new IsoObject
13.             {
14.                 IsoPosition = new Vector3(x, y, 0),
15.                 IsoSize = Vector3.one,
16.             };
17.  
18.             //error line
19.             ecb.AddSharedComponent(entityInQueryIndex, entity, new TestShared{Value = 1});
20.  
21.             ecb.AddComponent(entityInQueryIndex, entity, d);
22.             ecb.AddComponent<PosChangedTag>(entityInQueryIndex, entity);
23.             }
24. }

 

Not supported in Entities 0.51, and not the Burst Team's fault.

 

Thanks
