RAP RDP Service C# Skeleton

This directory contains an inactive C# RDP service research scaffold.

Status: inactive research scaffold. It is not wired into the runtime stack and does not replace the current C++ worker.

Purpose

The current C++ worker remains the active RDP runtime. The active performance direction is C++ RDP service internals, documented in:

• docs/architecture/RDP_SERVICE_CPP_PERFORMANCE_TARGET.md

This C# scaffold is retained only as non-runtime research context. It must not be used for implementation unless explicitly re-approved.

Any future alternative service would still need to keep:

• backend control-plane contracts
• worker lease/assignment model
• direct worker WSS data-plane contract
• fallback backend gateway
• session lifecycle semantics

Rules

• No FreeRDP dependency in this service.
• No third-party RDP protocol library.
• RDP protocol details stay behind service boundaries.
• Cluster transport is not redesigned here.
• Current C++ worker remains the active and intended runtime direction.
• Do not continue this C# scaffold unless explicitly re-approved.

Build

dotnet build workers/rdp-service-csharp/src/Rap.Rdp.Service/Rap.Rdp.Service.csproj

Current Limitations

• No RDP handshake yet.
• No NLA/CredSSP yet.
• No graphics protocol implementation yet.
• No direct WSS binding yet.
• No worker registration yet.
