Full skill instructions
This skill provides expert guidance for Azure SignalR Service. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.
IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g.,
L35-L120), useread_filewith the specified lines. For categories with file links (e.g.,[security.md](security.md)), useread_fileon the linked reference file
IMPORTANT for Agent: If
metadata.generated_atis more than 3 months old, suggest the user pull the latest version from the repository. Ifmcp_microsoftdocstools are not available, suggest the user install it: Installation Guide
This skill requires network access to fetch documentation content:
mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.| Category | Lines | Description |
|---|---|---|
| Troubleshooting | L37-L45 | Diagnosing and fixing SignalR issues: connectivity and message delivery problems, live trace and Azure Monitor logs, common error patterns, and best practices for reliable operation. |
| Best Practices | L46-L51 | Guidance on safely shutting down SignalR app servers and managing client lifecycle events, including detecting, handling, and recovering from client disconnects and reconnects. |
| Decision Making | L52-L56 | Guidance on choosing the right SignalR Service mode (Default/Serverless/Classic) and configuring availability zones/zone redundancy for high availability and resilience. |
| Architecture & Design Patterns | L57-L63 | Patterns for scaling and sharding SignalR, designing resilient multi-region topologies, and architecting high-availability, high-throughput ASP.NET Core SignalR apps with Azure SignalR. |
| Limits & Quotas | L64-L70 | Message/connection billing rules, capacity planning, throughput limits, and how to scale Azure SignalR instances within quota and performance constraints. |
| Security | L71-L92 | Securing Azure SignalR: auth with Entra ID/managed identities, keys and rotation, network/private endpoints/NSGs, WAF, Key Vault access, RBAC, cross-tenant, and Azure Policy compliance. |
| Configuration | L93-L104 | Configuring SignalR apps: connection strings, upstream endpoints, custom domains, monitoring/metrics, negotiation endpoints, Functions bindings, and using the local emulator. |
| Integrations & Coding Patterns | L105-L120 | Patterns and APIs for integrating SignalR with servers and gateways: SDK usage, client management, REST data-plane versions, and wiring events through Event Grid, API Management, and Application Gateway. |
| Deployment | L121-L131 | Deploying and managing Azure SignalR via CLI, ARM/Bicep templates, autoscale setup, regional moves, and end-to-end web app deployment (incl. GitHub auth) |
