FieldCure.AssistStudio.Core

Platform-agnostic AI provider client library for .NET — Claude, OpenAI, Gemini, Ollama, and any OpenAI-compatible endpoint.

NuGet License: MIT

Features

  • Multi-Provider — Claude, OpenAI, Gemini, and Ollama built-in. Implement IAiProvider to add your own.
  • Streaming — Real-time token-by-token responses via IAsyncEnumerable<string>.
  • Vision & Documents — Attach images, PDFs, and DOCX files to conversations.
  • Tool / Function Calling — Define tools with IAssistTool for provider-invoked function calls.
  • Token Tracking — Input/output token counts exposed after every request.
  • Platform-Agnostic — Targets net8.0 with no Windows dependency. Use from console apps, servers, or any .NET project.

Install

dotnet add package FieldCure.AssistStudio.Core

Quick Start

using FieldCure.AssistStudio.Models;
using FieldCure.AssistStudio.Providers;

// Create a provider
var provider = new ClaudeProvider(apiKey: "sk-ant-...", modelId: "claude-sonnet-4-20250514");

// Simple completion
var request = new AiRequest("What is the capital of France?");
var response = await provider.CompleteAsync(request);
Console.WriteLine(response.Content);

// Streaming
await foreach (var token in provider.StreamAsync(request))
{
    Console.Write(token);
}

Supported Providers

Provider Streaming Vision Documents Tool Calling
Claude (Anthropic) Yes Yes Yes Yes
OpenAI (+ compatible) Yes Yes Yes Yes
Gemini (Google) Yes Yes Yes Yes
Ollama (local) Yes Model-dependent Model-dependent Model-dependent

OpenAI provider works with any OpenAI-compatible API (Groq, Azure OpenAI, etc.) by setting a custom baseUrl.

Custom Provider

Implement IAiProvider to integrate any AI service:

public class MyProvider : IAiProvider
{
    public string ProviderName => "MyService";
    public string ModelId => "my-model-v1";
    public TokenUsage? LastUsage { get; private set; }
    // ... implement CompleteAsync, StreamAsync, ListModelsAsync, ValidateConnectionAsync
}

Key Types

Type Description
IAiProvider Provider interface — completion, streaming, model listing
IAssistTool Tool/function calling interface
AiRequest / AiResponse Request and response models
ChatMessage Conversation message with role, content, and attachments
ProviderPreset Saved provider configuration (model, temperature, etc.)
Profile System prompt + tool selection preset
ConversationManager Save/load conversations in .astx format
ProviderFactory Create IAiProvider from a ProviderPreset
