AyCode.Blazor — Domain Rules

This is the single source of truth for Blazor/MAUI UI domain rules. Do not duplicate these elsewhere. For core framework rules see: ../AyCode.Core/.github/copilot-instructions.md For detailed docs see: README.md → docs/

DevExpress Components

1. DevExpress Blazor 25.1.3 — always use DxGrid, DxFormLayout, etc. Do NOT mix with generic Blazor component libraries.
2. Grid system uses AcSignalRDataSource for real-time data — grids fetch data via SignalR, not REST.
3. CardView components wrap DevExpress grids with card-style layout for mobile-friendly display.

Architecture

4. Blazor.Components is the main UI library — both Blazor Server and MAUI Hybrid consume it.
5. Blazor.Models = shared view models (client + server). Blazor.Models.Server = server-only scaffolding.
6. MAUI.Core targets Android (API 33+), iOS (15.0+), Windows (10.0.19041+) via platform folders.
7. Controllers project is scaffolding — do not add business logic here.

Serialization in UI

8. SignalR uses AcBinaryHubProtocol (custom binary) — not the default JSON protocol.
9. Grid filters use AcExpressionNode serialization — LINQ expressions are serialized and sent to server.

Conventions

10. Do not suggest removal/rollback as a solution — find a fix for the problem.
11. All DLL references to AyCode.Core projects are via DllReference (not ProjectReference) — this is intentional.
