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.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213> **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L37-L45 | Diagnosing and fixing SignalR issues using logs and live trace, covering connectivity, message delivery, common errors, and FAQ-style troubleshooting tips. |24| 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. |25| Decision Making | L52-L57 | Guidance on choosing the right SignalR Service mode (Default/Serverless/Classic) and configuring availability zones/zone redundancy for high availability and resilience. |26| Architecture & Design Patterns | L58-L64 | Patterns for scaling and sharding Azure SignalR, designing multi-instance topologies, and building resilient, disaster-ready SignalR deployments for ASP.NET Core apps |27| Limits & Quotas | L65-L71 | Message/connection billing rules, capacity planning, throughput limits, and how to scale Azure SignalR instances within quota and performance constraints. |28| Security | L72-L93 | Securing Azure SignalR: auth with Entra ID/managed identities, keys and rotation, network/private endpoints/NSGs, WAF, Key Vault, RBAC, cross-tenant access, and Azure Policy compliance. |29| Configuration | L94-L105 | Configuring SignalR apps: connection strings, upstream endpoints, custom domains, monitoring/metrics, negotiation endpoints, Functions bindings, and using the local emulator. |30| Integrations & Coding Patterns | L106-L120 | Using SignalR from servers and REST, managing clients, integrating with Event Grid, API Management, Application Gateway, and detailed data-plane REST API references |31| 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.
