Answer to Question #258333 in C# for Reeke

Question

All the requirements from Task 1 must still be met by the program, with the following changes and additions:

1. The software shall persist the data in a SQL database.

2. The user shall be able to register with a username and password.

3. The software shall store only the hash of the password in the database.

4. The user shall be able to log into the software with their username and password.

5. The user shall only be able to see their own data and never that of other users.

Non-functional requirements:

1. The application should make use of the custom class library developed in Task 1. You may update the class library as necessary for the new functionality.

2. You can choose whether to access the database using the ADO.NET connected layer, ADO.NET disconnected layer or Entity Framework.

3. Regardless of database access technology, the application should use multi-threading to ensure that the user interface never becomes unresponsive while retrieving or storing information.

      Console.Write("Enter your username: ");
      user_n=Console.ReadLine();
      Console.Write("Enter your password: ");
      pass=Console.ReadLine();
      
      if(user_n==username & pass==password){
          Console.WriteLine("Logging sucessful. Your details are as follows: ");
