2. How the app works

Database:

The chat uses SQL Server DB with Entity Framework for data management. The repository design pattern is implemented to encapsulate SQL queries into specific repository classes, ensuring code reuse and maintainability.

Messaging:

SignalR API is utilized for real-time messaging, supporting WebSockets, Server-Sent Events, and Long Polling. SignalR ensures seamless connection fallback and handles disconnected clients effectively.

Model objects:

AutoMapper API is employed for mapping between model objects and DTOs, minimizing code duplication and simplifying complex mappings where necessary. ViewModel convention is used for read-only views of model data.

Motivation:

The project was motivated by a desire to understand messaging applications and technologies such as WebSocket in practice. It serves as a practical application to explore and implement these protocols while enhancing skills in MVC development.
