LogicGrid

A modular .NET toolkit for building agent and RAG (retrieval-augmented generation) applications. Pure C#, multi-targeted to netstandard2.0, net6.0, and net8.0, with zero hidden dependencies.

Free to use today, including in commercial products. See LICENSE.txt.

Packages

Package Description
LogicGrid.Core Agents, admins, providers, orchestration, events, logging, tracing.
LogicGrid.Memory Embeddings and vector stores (in-memory, Qdrant, pgvector). Hybrid search.
LogicGrid.Rag RAG pipeline — document loading, chunking, embedding, retrieval.
LogicGrid.Tools Built-in tools — web search, HTTP, datetime, calculator.
LogicGrid.Mcp MCP client — consume any MCP server as agent tools.

Quickstart

dotnet add package LogicGrid.Core

using LogicGrid.Core.Agents;
using LogicGrid.Core.Llm;

var llm = LlmClientBase.Ollama("llama3.2");

IAgent agent = new Agent<string>(
    name: "Helper",
    description: "Answers questions concisely.",
    systemPrompt: "Answer in one short sentence.",
    llm: llm);

Console.WriteLine(
    await agent.RunAsync("Capital of France?", new AgentContext()));

Full documentation: logicgrid.dev/docs

LogicGrid.Memory.Search adds a sparse keyword retriever (BM25) alongside the dense vector retriever, fused via Reciprocal Rank Fusion (RRF).

var store = new HybridVectorStore(new InMemoryVectorStore());
var pipeline = new RagPipeline(embedder, store);

await pipeline.IngestAsync("docs/manual.txt");

var results = await pipeline.HybridSearchAsync("SKU-4421 pricing", topK: 5);
foreach (var r in results)
{
    Console.WriteLine($"{r.RrfScore:F4}  dense={r.DenseScore:F3}  sparse={r.SparseScore:F3}");
    Console.WriteLine(r.Document.Text);
}
  • Dense retrieval — cosine similarity over embeddings; great at semantic matches.
  • Sparse retrieval — BM25 over tokenized text; great at exact terms (codes, IDs, proper nouns).
  • RRF — parameter-free merge of both ranked lists. k = 60 by default.

HybridVectorStore implements IVectorStore, so it's a drop-in replacement for the in-memory store. RagPipeline.HybridSearchAsync falls back to dense-only results when constructed with a plain IVectorStore.
