| description | Use this agent when working on legacy .NET Framework 4.8 enterprise applications that require maintenance, modernization, or integration with Windows-based infrastructure. Specifically:\n\n<example>\nContext: User has a legacy ASP.NET Web Forms application running on .NET Framework 4.8 that needs security updates and performance optimization.\nuser: "We have a 10-year-old Web Forms application with ViewState bloat and some outdated security patterns. How can we modernize it without a complete rewrite?"\nassistant: "I'll use the dotnet-framework-4.8-expert agent to analyze the architecture, identify security vulnerabilities, and recommend modernization strategies while maintaining backward compatibility."\n<commentary>\nSince this involves legacy .NET Framework 4.8 Web Forms with specific modernization constraints, use the dotnet-framework-4.8-expert agent rather than a general C# developer.\n</commentary>\n</example>\n\n<example>\nContext: User is implementing a WCF service that needs to interoperate with legacy Windows services and COM components.\nuser: "We need to create a WCF service that talks to our old COM objects and Windows services. What's the best approach?"\nassistant: "I'll use the dotnet-framework-4.8-expert agent to design the WCF service architecture with proper interop patterns and Windows service integration."\n<commentary>\nWCF services with COM interop and Windows service integration are specialized concerns within .NET Framework 4.8. Use this agent for legacy Windows integration patterns.\n</commentary>\n</example>\n\n<example>\nContext: User has an enterprise application running on .NET Framework 4.8 with performance issues and legacy deployment constraints.\nuser: "Our ERP system is running slow on .NET Framework 4.8. We're locked into Windows Server 2012 R2. What optimizations are realistic?"\nassistant: "I'll use the dotnet-framework-4.8-expert agent to identify bottlenecks, optimize database access, tune garbage collection, and work within your framework and infrastructure constraints."\n<commentary>\nLegacy enterprise applications with Windows infrastructure constraints require understanding of .NET Framework 4.8 specifics, not just general C# knowledge. Use this specialized agent.\n</commentary>\n</example> |
