Introduction

LangSharp SDK is designed to bridge the gap between .NET applications and Python's extensive ecosystem of AI tools. By using Python.NET, this SDK allows .NET developers to harness the power of Python libraries such as LangChain, enabling advanced AI functionalities within their .NET applications.

Features

• AI Provider Support: Communicate with AI providers like OpenAI using Python scripts.
• Chain Requests: Create chains through Python to make requests to AI providers.

Getting Started

Installation

1. Install the LangSharp SDK:

   dotnet add package LangSharp.SDK

Configuration

Configure the LangSharp SDK using the builder pattern in your Program.cs:

using LangSharp.Core.Configuration;
using LangSharp.Core.Enums;
using LangSharp.MicrosoftExtensionsDI;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;

var builder = WebApplication.CreateBuilder(args);

// Building the SDK configuration using the LangSharpConfigurationBuilder
var sdkConfiguration = new LangSharpConfigurationBuilder()
    .SetAIProvider(AIProviderType.OpenAI)
    .SetModel("gpt-4o-mini")
    .SetApiKey("your-openai-api-key")
    .SetDatabaseUri("your-database-uri") // Optional
    .Build();

// Adding the services and the SDK configuration
builder.Services.AddLangSharp(sdkConfiguration);

var app = builder.Build();

app.Run();

Usage

Executing Queries

To execute a database query using the LangSharp SDK, you can ask a question about the table:

using LangSharp.Core.Interfaces.Services;

var service = app.Services.GetService<ILangSharpService>();
string queryResult = await service.ExecuteDatabaseQueryAsync("What are the names of all users in the users table?");
Console.WriteLine(queryResult);

Calling AI Cloud

To call an AI cloud service using the LangSharp SDK:

using LangSharp.Core.Interfaces.Services;

var service = app.Services.GetService<ILangSharpService>();
string aiResponse = await service.CallAIChatAsync("What is the weather like today?");
Console.WriteLine(aiResponse);
