SignalR & Azure SignalR Service

Backend

Real-time messaging for .NET and Azure-hosted apps

Overview

ASP.NET Core SignalR and the Azure SignalR Service managed backplane power live dashboards, notifications, and collaborative UIs in ConnectSoft templates—scale-out without operating your own WebSocket farm when Azure hosts the connection layer.

Factory microservices use SignalR hubs on .NET 10 with Microsoft Entra ID-backed auth; we add Azure SignalR Service when connection count, regional presence, or operational offload justify the managed service. Redis backplane remains an option for self-hosted scale-out patterns.

Client engagements get explicit transport, reconnect, and telemetry rules in Application Insights so real-time features do not become silent failure points under load.

If live updates are core to your product, we wire SignalR the same way as the rest of your Azure platform—not as a one-off script on the side.

Why we use it:

  • WebSocket and fallback transports
  • Redis scale-out in template options
  • Fits ASP.NET Core hosting and auth
  • Used when live updates beat polling
  • Aligns with ASP.NET Core hosting and OpenAPI contracts in our templates
  • Observability hooks for Application Insights and OpenTelemetry
  • Clear Factory default versus client-specific adoption boundaries
