Implemented complete C# gRPC service wrapping GeViScope SDK: ✅ gRPC Protocol Definitions (T011-T014): - common.proto: Status, Error, Timestamp messages - camera.proto: CameraService with ListCameras, GetCamera RPCs - monitor.proto: MonitorService with ListMonitors, GetMonitor RPCs - crossswitch.proto: CrossSwitchService with ExecuteCrossSwitch, ClearMonitor, GetRoutingState, HealthCheck RPCs ✅ SDK Wrapper Classes (T015-T021): - GeViDatabaseWrapper.cs: Connection lifecycle with retry logic (3 attempts, exponential backoff) - StateQueryHandler.cs: GetFirst/GetNext enumeration pattern for cameras/monitors - ActionDispatcher.cs: CrossSwitch and ClearVideoOutput action execution - ErrorTranslator.cs: SDK errors → gRPC status codes → HTTP status codes ✅ gRPC Service Implementations (T022-T026): - CameraService.cs: List/get camera information from GeViServer - MonitorService.cs: List/get monitor/viewer information from GeViServer - CrossSwitchService.cs: Execute cross-switching, clear monitors, query routing state - Program.cs: gRPC server with Serilog logging, dependency injection - appsettings.json: GeViServer connection configuration Key Features: - Async/await pattern throughout - Comprehensive error handling and logging - In-memory routing state tracking - Health check endpoint - Connection retry with exponential backoff - Proper resource disposal Architecture: FastAPI (Python) ←gRPC→ SDK Bridge (C# .NET 8.0) ←SDK→ GeViServer Ready for Phase 3: Python API Foundation 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
