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

## Add functionality

There may be situations when we need to extend a class or struct’s functionality. There are several approaches we could take.

### Change the source code

We could go to the source code of the type and make whatever changes we need. Consider the following `Printer` class. Its purpose is to print the `Message` property in a variety of ways. If we need additional functionality, we can simply add another method or edit existing ones:
