This is a WPF Windows Desktop application that initially followed an online tutorial for the "Friend Organiser" use case, but I extended the tutorial to convert the WPF Desktop App to use an API service for its data persistence instead of local ORM direct to database. I've also recreated the server endpoint in Python using Flask, and Ruby On Rails using Active Record, for no reason whatsoever.

Frequently used commands (for the .NET backend)\

Create a data migration

dotnet ef migrations add InitialCreate --project ./Core/FriendOrganiser.Persistence/FriendOrganiser.Persistence.csproj --startup-project ./API/FriendOrganiser.API/FriendOrganiser.API.csproj

Run migrations against the database

dotnet ef database update --project ./Core/FriendOrganiser.Persistence/FriendOrganiser.Persistence.csproj --startup-project ./API/FriendOrganiser.API/FriendOrganiser.API.csproj

(For the Python backend)

Set up a MariaDB instance and use the "create-and-seed-database.sql" file to initialise the database. The connection details can be maintained in the ExecuteDatabaseStatement.py file

(For the Ruby backend)
