Activation-factory constructors taking arrays of non-blittable structs, mapped value types (DateTime/TimeSpan), or HResult/Exception elements hardcoded nint InlineArray storage and void** CopyToUnmanaged/Dispose data pointers, so the array marshaller's UnsafeAccessor failed to bind at runtime (Method not found: ...ArrayMarshaller.Dispose). Route the constructor's PassArray storage, CopyToUnmanaged, and finally cleanup through the element-kind-aware helpers (GetArrayElementStorageType and typed data-pointer/cast selection), mirroring the RCW caller. Add a TestComponentCSharp constructor and TestNonBlittableArrayConstructor test covering all three element kinds. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Drop the separate dataCastType and derive the cast inline from dataParamType. Keep the if/else style (matching the RCW caller's equivalent logic) with the same IDE0045 suppression. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
