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

We’ve learned about the primitive types and have also worked with classes and structs. It’s time to classify them all. All data types in .NET are divided into two categories: value types and reference types.

When we create a variable of a value type, a place in memory is allocated for that value and the slot contains the actual data.
 
> **Note:** All primitive types like `int`, `double`, `bool`, `float`, and `char` are examples of value types. When we create a `struct`, we create a value type. Primitive types are essentially structs.

Consider the following example:

```C#
int age = 25;
```

The `age` variable is a slot of memory, and that slot contains the actual value which, in this case, is `25`.

Another important feature of value types is that they’re stored in the stack. The **stack** can be thought of as each method’s local memory (context).

```C#
static void Main()
{
	int age = 25;
}
```
