WPF app (.Net framework)
Login Window : use one single user, the credentials can be hard coded to check the input ones for the authentication.
Main Window :
Display the fields for just one record customerid , first name, last name, address, phone, comments.
Only field comments should be editable.
When ‘comments’ text is changed, a button ‘Save’ should be visible, and on button Save click, save the new value to DB.
Display a field/Dropdown menu with available values : Result1, Result2, Result3 When a value is selected, automatically save it to Table2.
*On table2 use a unique id generated from the wpf app, and each record should be related to Table1.
Nice to have : Logging mechanism (e.g write to log file for each login, or when a value is inserted to a table) using NLog.
Ø DB (SQL Server)
Use two tables one for basic contact information, and one to store the selected values from the Dropdown menu.
