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

Although C# is a statically-typed language, some dynamic features have been added in recent versions of the language. A new functionality called Dynamic Language Runtime (DLR) was added in .NET 4.0.

To understand the meaning of this feature, we should consider the difference between statically and dynamically-typed languages. In languages with static typing, the identification of all types and their members (properties, methods) occurs at the compilation stage. Consider the following `Course`:

```C#
public class Course
{
	public string Title { get; set; }
}
```

We have access to the `Title` property when we create an instance of the class. If we try to access a member that doesn’t exist, we get a compile-time error:
