[GenerateAuthoringComponent] on 0.17.0-preview.41 does not support ISharedComponentData anymore

[GenerateAuthoringComponent] on 0.17.0-preview.41 does not support ISharedComponentData anymore

I can replicate 2 different error msgs even.

ArmySharedData.cs(13,9): error ArmySharedData.cs(13,9): error DC3003: ArmySharedData has the [GenerateAuthoringComponent] attribute, and must therefore implement either the IComponentData interface or the IBufferElementData interface.

for:

Code (CSharp):

1.     [Serializable]
2.     [GenerateAuthoringComponent]
3.     public struct ArmySharedData : ISharedComponentData, IEquatable<ArmySharedData>
4.     {
5.         public int FactionId;
6.  
7.         public bool Equals(ArmySharedData other)
8.         {
9.             return FactionId == other.FactionId;
10.         }
11.  
12.         public override bool Equals(object obj)
13.         {
14.             return obj is ArmySharedData other && Equals(other);
15.         }
16.  
17.         public override int GetHashCode()
18.         {
19.             return FactionId;
20.         }
21.     }

and:

(0,0): error error DC3003: ArmySharedData has the [GenerateAuthoringComponent] attribute, and must therefore implement either the IComponentData interface or the IBufferElementData interface.

for:

Code (CSharp):

1.     [Serializable]
2.     [GenerateAuthoringComponent]
3.     public struct ArmySharedData : ISharedComponentData
4.     {
5.         public int FactionId;
6.     }
7.  

This seems to be a regression since it is not mentioned in the changelogs.

 

The DC300X static analysis rules were added in 0.17.

I had a read through their documentation and change logs and I could only see it mentioned working for IComponentData and IBufferElement so I'm not sure it was ever supported, even if it happened to work.

 

Thx tertle.

Probably worth noting that recently updating the package i even found that i was not using the [GenerateAuthoringComponent] workflow with ISharedComponentData in the Unity Editor anymore (or even ever) and all usage was only form code.
Just deleting [GenerateAuthoringComponent] from ISharedComponentData now. So this workflow seems to be unsupported before 0.17 to me but not detected as an error. Which changed with version 0.17
