• Add integration tests for custom attribute array encoding (once PR [Repo Assist] Fix custom attribute encoding for generative type providers #463 is merged)

Run History

2026-02-28 08:15 UTC — Run

• 🔧 Created PR [Repo Assist] Add isStruct convenience parameter to ProvidedTypeDefinition #464: Add isStruct convenience parameter to ProvidedTypeDefinition — adds ?isStruct: bool to both public constructors, sets SequentialLayout, defaults base to ValueType; 4 new tests; 108/108 pass

2026-02-27 08:24 UTC — Run

• 🔍 Verified no new activity since 2026-02-26 — PRs [Repo Assist] Prepare release 8.3.0 #462/[Repo Assist] Fix custom attribute encoding for generative type providers #463 still open as drafts, CI pending
• 🔍 Investigated struct support in ProvidedTypeDefinition: IsValueTypeImpl() already delegates to base type; assembly writer correctly sets parent via SetParent; struct support works today by setting baseType = Some typeof(System.ValueType); an isStruct convenience parameter + TypeAttributes.SequentialLayout + tests would be a clean enhancement

2026-02-26 16:08 UTC — Run

• 🔍 Status check — both PRs ([Repo Assist] Prepare release 8.3.0 #462, [Repo Assist] Fix custom attribute encoding for generative type providers #463) clean and awaiting review; no new issues or comments since last run
• 🔍 Investigated potential improvements: struct type support gap noted; no actionable immediate fix
