## What it is
OllamaSharp is a .NET client library providing bindings for the entire Ollama API, including chat, generation, embeddings, and model management. It supports streaming responses, tool/function calling with source generators, vision models, and integrates with Microsoft.Extensions.AI and Semantic Kernel.

## Use cases
- call ollama from c#
- stream llm chat responses in .net
- generate embeddings with ollama in dotnet
- pull and manage ollama models programmatically
- add function calling to a .net chatbot
- use local llms in an asp.net app
- build a rag pipeline with ollama embeddings

## When to choose
- you are building a .NET application that talks to a local or remote Ollama server
- you want full Ollama API coverage with streaming and progress reporting
- you need Microsoft.Extensions.AI/IChatClient compatibility or Semantic Kernel integration
- you want tool calling with source-generator support in C#

## When to avoid
- you use Python, Node.js, or another non-.NET language
- you need a client for OpenAI or other LLM providers rather than Ollama
- you want a ready-made chat UI rather than an API client library
