    Semantic Kernel - Pros & Cons

    Pros

    • ✓Plugin system lets you expose existing C#/Python methods to LLMs with a single decorator — minimal refactoring needed
    • ✓First-class .NET support with dependency injection, middleware patterns, and enterprise conventions C# teams already know
    • ✓Azure OpenAI deep integration with managed identity, content safety filters, and enterprise deployment patterns baked in
    • ✓OpenTelemetry-based observability provides production-grade tracing and metrics without third-party tooling

    Cons

    • ✗Planner reliability varies — automatic function chaining can produce unexpected plans requiring careful prompt engineering
    • ✗Heavier abstraction layer than direct API calls — adds complexity for simple use cases that don't need plugins
    • ✗Community and ecosystem are smaller than LangChain's, resulting in fewer third-party integrations and examples
