Key Components

• Configure Method:
  • Maps the Apartment entity to the apartments table.
  • Configures the primary key and properties like Name and Description with specific conversions.
  • Configures owned entities like Address, Price, and CleaningFee with custom conversions for currency.
  • Adds a Version property for pessimistic concurrency control.
