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

# Statements and code blocks

C# code files are text files with .cs extension. They contain instructions that're compiled to #key# IL:Intermediate Language #key# code.

**Statements** are the basic building blocks of C# source code. A statement can be some action, such as an arithmetic operation, a method invocation, or a variable declaration and assignment.

```C#
Console.WriteLine("This is a statement.");
``` 

Like in C and C++, every statement must be followed by a semicolon (`;`). Leaving them out results in compilation errors, and our program won’t compile to IL.

We can combine a set of instructions into blocks of code. To create a code block, we enclose our statements in curly braces.

```C#
{
	Console.WriteLine("I am inside a block!");
	Console.WriteLine("Me too.");
}
```

Blocks can contain other blocks. Essentially, both a `class` and a method can be seen as code blocks. A `class` contains a method, and a method contains instructions within its curly braces.
