.NET is Microsoft’s free and open source framework for developing native software applications on Linux, macOS, and Windows. The power of cross-platform development allows developers to design, code, and run programs on a wide array of platforms.

This course is an introduction to developing .NET applications using C#. You’ll start start with a comprehensive review of C# and computer programming fundamentals: data types, conditionals, loops, methods, and more. You’ll then review the basics of object-oriented programming before diving into methods, exception handling, delegation, and events. With this foundation, you’ll continue building interfaces, collections, database operations, and multithreading. You’ll wrap up with process improvements using dynamic binding, garbage collection, and unmanaged resources.

By the end of this course, you’ll have hands-on experience with C# and .NET, and be ready to build applications using object-oriented programming principles on almost any platform.

# Overview

Let’s see interfaces in action by jumping into the code. We have the `ElectricCar` class that simulates an electric car. Run the code to see what this class can do.

using System;

namespace Interfaces
{
    public class ElectricCar
    {
        public bool CarOn { get; private set; }

        public void StartTheCar(int keyId)
        {
            if (KeyValid(keyId))
            {
                CarOn = true;
                Console.WriteLine("Starting the car.");
            }
            else
            {
                Console.WriteLine("Where are your keys?");
            }
        }

        public void TurnTheCarOff()
        {
            CarOn = false;
            Console.WriteLine("Car off.");
        }

        public void Drive()
        {
            if (CarOn)
            {
                Console.WriteLine("Car driving.");
            }
            else
            {
                Console.WriteLine("First, you have to start the car.");
            }
        }

        private bool KeyValid(int keyId)
        {
            if (keyId == 14) return true;
            return false;
        }
    }
}


using System;

namespace Interfaces
{
    class Program
    {
        static void Main(string[] args)
        {

            var car = new ElectricCar();
            Console.WriteLine("We've got a Tesla.");
            Console.WriteLine("Attempting to drive it.");
            car.Drive();
            car.StartTheCar(15);
            car.StartTheCar(14);
            car.Drive();
            car.TurnTheCarOff();
        }
    }
}

Our car can be started, driven, and turned off. There’s also logic that prevents driving without first starting the car. Now, let's add the `TV` class into our set:
