Features

This project framework provides the following features:

• Modern .NET application architecture with .NET Aspire
• Various search capabilities (keyword search, semantic search)
• Integration with multiple AI models (GPT-4o, DeepSeek-R1, etc.)
• Vector database implementations (In Memory, Azure AI Search, Chroma DB and others)
• Real-time audio capabilities
• Model Context Protocol (MCP) server and client implementation

eShopLite Scenarios

The project includes several scenarios demonstrating different capabilities:

| Scenario | Description | Key Technologies | |----------|-------------|-----------------| | 01 - Semantic Search | A reference .NET application implementing an eCommerce site with Search features using Keyword Search and Semantic Search. | .NET Aspire, OpenAI GPT-4.1-mini, In-memory Vector DB | | 02 - Azure AI Search | Implements an eCommerce site with Keyword Search using SQL queries and Semantic Search with Vector Database and Azure AI Search. | Azure AI Search, OpenAI Embeddings, SQL Server | | 03 - Realtime Audio | Extends the eCommerce site with advanced search features and real-time audio capabilities powered by the GPT-4o Realtime Audio API. | GPT-4o Realtime Audio API, Audio in Blazor, .NET Aspire | | 04 - Chroma DB | Implements semantic search functionality using Chroma DB, an open-source database designed for AI applications. | Chroma DB, OpenAI Embeddings, .NET SDK | | 05 - DeepSeek-R1 | Demonstrates integration of the DeepSeek-R1 model for enhanced semantic understanding and search capabilities. | DeepSeek-R1, .NET Aspire, Vector Embeddings | | 06 - Model Context Protocol (MCP) | Implements the Model Context Protocol (MCP) for advanced AI interactions with MCP Servers and MCP Clients. | Model Context Protocol, Function Calling, SSE Events | | 07 - Agents Concurrent | Demonstrates concurrent agent orchestration and advanced AI agent collaboration patterns. | .NET Aspire, Multi-Agent Systems, Orchestration | | 08 - SQL Server 2025 | Demonstrates the use of vector search and vector indexes in the SQL Database Engine | SQL Server 2025, Vector Search, Vector Indexes | | 09 - Azure App Service | Shows how to deploy a .NET Aspire multi-service eCommerce app to Azure App Service, using SQLite for data and integrating AI search. | Azure App Service, .NET Aspire, OpenAI, SQLite | | 10 - A2A Network | Demonstrates advanced agent-to-agent (A2A) communication and orchestration patterns in .NET Aspire, including multi-agent collaboration and reasoning. | .NET Aspire, Multi-Agent Systems, A2A Protocol | | 11 - GitHub Models | Local-first AI development using GitHub Models during local runs, with automatic switch to Azure OpenAI when deployed. | .NET Aspire, GitHub Models, Azure OpenAI | | 12 - Azure Functions | Optional Azure Functions façade for semantic search and an alternate deployment boundary for vector search. | Azure Functions, .NET Aspire, Azure OpenAI |

Getting Started

Prerequisites

• .NET 9
• Docker Desktop or Podman
• Azure Developer CLI (azd) (for Azure deployment)
• Git

Installation

1. Clone the repository:

   git clone https://github.com/Azure-Samples/eShopLite.git
   

2. Navigate to the scenario directory of interest:

   cd eShopLite/scenarios/[scenario-folder]
   

3. Login to Azure:

   azd auth login
   

4. Provision and deploy all the resources:

   azd up
   

   It will prompt you to provide an azd environment name (like "eShopLite"), select a subscription from your Azure account, and select a location where the necessary models, like gpt-4.1-mini and ADA-002 are available, a sample region can be "eastus2".

Quickstart

1. Navigate to a specific scenario folder (e.g., scenarios/01-SemanticSearch/)
2. Follow the README instructions in that scenario folder
3. Run the solution using dotnet run in the appropriate host project folder

Demo

To run the demo, follow these steps:

1. Navigate to the specific scenario folder
2. Follow the "Run the solution" instructions in that scenario's README
3. Access the application via the URLs provided in the console output
