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 this lesson, we’ll learn about casting and the explicit implementation of interfaces. We’ll use the following interface as an example while exploring different concepts:

namespace Interfaces
{
    interface INumeric
    {
        int ToInt32();
        long ToInt64();
    }
}

# Access modifiers

Notice that interface members don’t have access modifiers. They’re `public` by default because the goal of an interface is to be implemented by other classes.

Beginning with C# 8.0, it’s possible to modify interface members with access modifiers. For instance, we can make methods or properties `private`:

```C#
namespace Interfaces
{
    interface INumeric
    {
        private int ToInt32();
        long ToInt64();
    }
}
```

We ‘ll rarely need to have `private` interface members, though.
