AI-powered chatbot built with ASP.NET Core + Blazor + .NET Aspire + Ollama, running entirely locally without external APIs.

Technologies Used:

• ASP.NET Core
• Blazor Server
• .NET Aspire
• Ollama
• Docker
• Microsoft.Extensions.AI

How it Works:

• The user sends a message from the chat UI.
• The request is processed by the Blazor frontend.
• The message is forwarded to the AI model via IChatClient.
• Ollama runs the LLM locally in a container.
• The response is returned and displayed in the UI.

Setup & Run

1. Prerequisites: .NET 8+ Docker Desktop WSL2 enabled (for Docker)
2. Run the application dotnet run --project AspireOllamaChatbot.AppHost
3. Open in browser Aspire Dashboard → http://localhost:17250 Chat UI → https://localhost:7188

Notes: The first run may take several minutes as the model is downloaded. Ensure Docker is running before starting the application.

Future Improvements:

1. Streaming responses (real-time typing)
2. Chat history persistence
3. Integration with Flutter mobile app
4. Multiple model support
5. Authentication system
