eShopSupport

A sample .NET application showcasing common use cases and development practices for build AI solutions in .NET (Generative AI, specifically). This sample demonstrates a customer support application for an e-commerce website using a services-based architecture with .NET Aspire. It includes support for the following AI use cases:

Text classification, applying labels based on content
Sentiment analysis based on message content
Summarization of large sets of text
Synthetic data generation, creating test content for the sample
Chat bot interactions with chat history and suggested responses

This sample also demonstrates the following development practices:

Developing a solution locally, using small local models
Evaluating the quality of AI responses using grounded Q&A data
Leveraging Python projects as part of a .NET Aspire solution
Deploying the application, including small local models, to the Cloud (coming soon)

Architecture

Getting Started

Prerequisites

A device with an Nvidia GPU (see workaround for running on the CPU)
Clone the eShopSupport repository: https://github.com/dotnet/eshopsupport
Install & start Docker Desktop
Install Python 3.12.5

Windows with Visual Studio

Install Visual Studio 2022 version 17.10 or newer
- Select the following workloads:
  - ASP.NET and web development workload.
  - Python Development workload.
  - .NET Aspire SDK component in Individual components.

Mac, Linux, & Windows without Visual Studio

Install the latest .NET 8 SDK

Install the .NET Aspire workload with the following commands:

dotnet workload update
dotnet workload install aspire
dotnet restore eShopSupport.sln

(Optionally) Install Visual Studio Code with the C# Dev Kit extension

Install Python requirements

From the Terminal, at the root of the cloned repo, run:

pip install -r src/PythonInference/requirements.txt

Note: If the above command doesn't work on Windows, use the following command:

py -m pip install -r src/PythonInference/requirements.txt

Running the solution

Warning

Remember to ensure that Docker is started.

(Windows only) Run the application from Visual Studio:
- Open the eShopSupport.sln file in Visual Studio
- Ensure that AppHost is your startup project
- Hit Ctrl-F5 to launch .NET Aspire
Or run the application from your terminal:
```
dotnet run --project src/AppHost
```
then look for lines like this in the console output in order to find the URL to open the Aspire dashboard:
```
Login to the dashboard at: http://localhost:17191/login?t=uniquelogincodeforyou
```

You may need to install ASP.NET Core HTTPS development certificates first, and then close all browser tabs. Learn more at https://aka.ms/aspnet/https-trust-dev-cert
