This project is a .NET Web API application. It allows users to create and list expenses, ensuring that some validation rules are applied. I am using SQL Server Database to persist datas.

The ExpensesAPI project provides a REST API to:

• Create expenses
• List expenses

• Expenses: An expense is characterized by a user, date, type (Restaurant, Hotel, Misc), amount, currency, and a comment.
• Users: A user is characterized by a last name, first name, and a default currency for their expenses.

1. Creating an Expense:

   • An expense cannot have a date in the future.
   • An expense cannot be dated more than 3 months ago.
   • The comment is mandatory.
   • A user cannot declare the same expense twice (same date and amount).
   • The currency of the expense must match the user’s currency.

2. Listing Expenses

3. Creating Users

4. Listing Users

• Entity Framework Core
