SignalRConnect

SignalRConnect links Unreal to ASP.NET Core backends over SignalR. Invoke hub methods, receive server-to-client calls and pass structured values - with a clean split between core C++ and Blueprint layers.

Point the client at your ASP.NET Core hub, negotiate, and start calling: Invoke sends a hub method and returns the result asynchronously, Send fires and forgets, and On binds server-to-client callbacks. Blueprint value wrappers move arguments across cleanly, and the hub URL and query-parameter builders keep connection strings maintainable. The runtime core and Blueprint layer are separate modules, so C++ teams can go straight to the source.

If your studio runs .NET services, SignalRConnect makes Unreal a first-class SignalR citizen: push notifications and server events, matchmaking and session orchestration, live configuration, admin and telemetry dashboards, or enterprise visualization products backed by ASP.NET Core.

SignalRConnect is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- SignalR hub client (negotiate + JSON protocol)

- Invoke with results, Send, and On callbacks

- Blueprint value wrappers for hub arguments

- Hub URL builders and query-param helpers

- Separate runtime and Blueprint modules

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
