Semantic Kernel for .NET

Semantic Kernel for .NET

Trigger On

• adding AI-driven prompts, plugins, or orchestration to a .NET app
• reviewing kernel construction, service registration, or plugin usage
• building function-calling patterns with LLMs
• migrating older Semantic Kernel code to current APIs

Documentation

• Plugins and Functions
• Agent Functions
• GitHub Repository
• Microsoft Agent Framework

Core Concepts

Workflow

1. Build the Kernel with required services
2. Create Plugins with well-described functions
3. Configure Function Calling for automatic tool use
4. Handle Responses and manage conversation state
5. Test and Observe AI behavior with logging
6. For Semantic Kernel dotnet-1.79.0 and later, keep OpenAPI plugin server URL validation enabled, do not re-enable automatic redirects on the default HttpPlugin or WebFileDownloadPlugin clients without an explicit trusted-host policy, and use the current Microsoft Agent Framework-compatible migration samples when moving SK agent code to Agent Framework.
