Project Steps:

Done

Download and install Visual Studio or Visual Studio Code.
Download and install the .NET SDK.

Done

Open your chosen IDE (Visual Studio or Visual Studio Code).
Open a terminal in your IDE.
Type the following command to create a new console application:
```
dotnet new console -n SimpleToDoList
```
Navigate to the project directory:
```
cd SimpleToDoList
```

Done

Open the `Program.cs` file in your IDE.

Replace the existing code with the following:


using System;
using System.Collections.Generic;

namespace SimpleToDoList
{
    class Program
    {
        static void Main(string[] args)
        {
            List toDoList = new List();
            string command = "";

            Console.WriteLine("Simple To-Do List Application");
            Console.WriteLine("Commands: add [task], remove [task number], list, exit");

            while (command != "exit")
            {
                Console.WriteLine("Enter a command:");
                command = Console.ReadLine().Trim();
                
                if (command.StartsWith("add "))
                {
                    string task = command.Substring(4);
                    toDoList.Add(task);
                    Console.WriteLine($"Added task: {task}");
                }
                else if (command.StartsWith("remove "))
                {
                    if (int.TryParse(command.Substring(7), out int taskNumber) && taskNumber > 0 && taskNumber <= toDoList.Count)
                    {
                        string removedTask = toDoList[taskNumber - 1];
                        toDoList.RemoveAt(taskNumber - 1);
                        Console.WriteLine($"Removed task: {removedTask}");
                    }
                    else
                    {
                        Console.WriteLine("Invalid task number.");
                    }
                }
                else if (command == "list")
                {
                    Console.WriteLine("To-Do List:");
                    for (int i = 0; i < toDoList.Count; i++)
                    {
                        Console.WriteLine($"{i + 1}. {toDoList[i]}");
                    }
                }
                else if (command != "exit")
                {
                    Console.WriteLine("Unknown command.");
                }
            }

            Console.WriteLine("Exiting To-Do List Application.");
        }
    }
}

Save the file.

Done

In the terminal, type the following command to run your application:
```
dotnet run
```
Test the application by adding, listing, and removing tasks to ensure everything works as expected.
