# 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.
