CSharp-Compile-Run-code

.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.

Mastering C# and .NET

# Introduction

In a previous lesson, we touched upon the topic of type casting and saw some examples where we cast primitive types between one another:

```C#
byte age = 24;
int ageAsInt = age; // Implicit cast
```

In this lesson, we’ll discuss type casting in the context of classes. Consider a set of following classes:

namespace TypeCasting
{
    public class Car : Vehicle
    {
        public int NumberOfSeatbelts { get; set; }

        public Car()
        {
            NumberOfWheels = 4;
        }
    }
}

namespace TypeCasting
{
    public class Motorcycle : Vehicle
    {
        public Motorcycle()
        {
            NumberOfWheels = 2;
        }
    }
}

namespace TypeCasting
{
    public class Vehicle
    {
        public string Model { get; internal set; }
        public decimal Price { get; internal set; }
        public int NumberOfWheels { get; internal set; }
    }
}

These three classes can be visualized by the following inheritance hierarchy:
