+# C# Crash Course 🚀
+
+In this C# Crash Course, we'll go over the basics of C# so that you'll be ready to build out exciting web apps! We'll start by going through the key attributes of C#, syntax basics, and introduce you to OOP. In each section, we'll link you to some quick in-browser C# challenges so you can apply these concepts.
+
+## Topics you'll learn
+* Language attributes
+* Syntax basics
+* Object Oriented Programming
+
+---
+
+# Language attributes
+C# is a strongly typed, compiled, object oriented language. Let's break this down.
+## Strongly typed
+  In a **strongly typed** language, every variable has a defined type. Some of these types include:
+  * String, "Hello world!"
+  * Char, 'a'
+  * int, 3
+  * decimal, 1.5
+  * bool, True
+
+## Compiler 
+A **compiler** converts the code you write into a format that your computer can understand. After you write C# and build it, the C# compiler (called Roslyn) will analyze your code to check for any errors.
+
+---
+
+# The basics
+## 🌍 Hello World
+Here's a piece of code that will print "Hello world!" to the console.
+
+```csharp
+using System;
+
+Console.WriteLine("Hello world!");
+```
+
+## Keywords
+With C#, you use keywords like `using` and `Console`.
+**Keywords** are predefined, reserved identifiers that have special meanings to the compiler.
+
+## Accessing methods
+The `. (DOT)` in `Console.WriteLine` allows us to access methods and properties. In this example, `Console` is a type that represents the console window. `WriteLine` is a method of the Console type that prints a line of text to that text console.
+
+## Parameters
+In this example, we use parentheses pass a string as a parameter to `Console.WriteLine`.

+
+## Variables
+In C#, **variables** allow you to temporarily store a value in memory. In C#, you must declare a variable before using it. 
+  ```csharp
+  var cSharp = "really cool";
+  ```
+In this example, we created a string called `cSharp`. You can use the var keyword to declare local variables without explicitly giving them a type.
+  
+Variable names can contain alphanumeric characters and underscores, but no special characters. They also cannot be keywords.

+
+# Syntax cheat sheet
+## Semicolons
+  Every statement is ended by a semicolon
+   ```csharp
+   Console.WriteLine("there is a ';' at the end of this statement");
+   ```
+## Comments
+  You can make comments by using 2 slashes
+   ```csharp
+   // this is a comment is C#
+   ```
+## Case sensitive
+  C# is case sensitive! For example, a variable "cat" is completely different from a variable "CAT".
+    ```csharp
+    var cat = "meow";
+    ```
+    ```csharp
+    var CAT = "rawr";
+    ```
+

+
+## Decision logic
+In C#, you can build applications that employ decision-making logic so that your application performs different instructions based on a set of conditions. One way we do this is with an `if` statement. `if` statements are made up of three parts:
+* The if keyword
+* A Boolean expression between parenthesis ()
+* A code block defined by curly braces { }
+
+If there are multiple condition, you can utilize the `else if` and `else` statements. Basically, if the `if` statement fails, these other statements allow you to test against other conditions.
+You can imagine this in the context of a rock⛰️-paper📃-scissors✂️ game. Imagine you chose rock⛰️. 
+* `if` your opponent chooses scissors✂️, then you will win
+* `else if` your opponent also chooses rock⛰️, then you will tie
+* `else` your opponent chooses paper📃, then you will lose
+
+Each possible decision your opponent could make leads to a different outcome.
+
+
+## Boolean expressions
+  Booleans are expressions that return either `true` or `false`. They are often used to compare two or more things.
+  | symbol | what it does |
+  | --- | ---------- |
+  | < | less than |
+  | > | greater than |
+  | <= | less than or equal |
+  | >= | greater than or equal |
+  | == | equal |
+  | != | not equal |

+
+# Object Oriented Programming
+C# is an object-oriented language. 
+Objects are defined by **Classes**. In other words, an **Object** is an instance of a class.
+One way to think about this is that a class is like the blue prints for a house. The actual house that is built is an objects because it is an instance of this blue print.
+
+## Properties and methods
+Objects inherently have attributes. In C# we call these **properties**. The attributes of a house may be the number of doors, what color the house is painted, etc.
+
+We can also define **methods** which describe what an object can do. For example, you can sell your house. 
+
+To summarize these concepts using our house example,
+A Class is like a blueprint 📜
+An Object is an instance of this blueprint, or a house 🏠
+The Properties of a house could be the number of doors it has or the color it's painted 🚪 🎨
+A Method of our class is that we can sell our house 💸
+
+Let's look at an example House class:
+```csharp
+// The namespace declaration provides a way to logically organize your classes
+namespace Classes;
+
+public class House
+{
+  // House properties
+    public string Address { get; }
+    public int Size { get;}
+
+  // House methods
+    public void SellHouse(decimal amount, DateTime date)
+    {
+    }
+}
+```
+## Constructor
+We can define a **constructor** to allow us to create new House objects. 
+
+```csharp
+public House(string address, int squareFeet)
+{
+    this.Address = address;
+    this.Size = squareFeet;
+}
+```
+When we create an object with `new` this constructor will be called.
+```csharp
+using Classes;
+
+// Let's create a 1500 square foot house on Candy Cane Lane
+var house = new House("123 Candy Cane Lane", 1500);
+```
+
+## The .NET Class Library
+C# also has built in classes and functionality within the .NET Class Library. The .NET Class Library is a collection of thousands of classes containing tens of thousands of methods. These methods are created by Microsoft and are available for use in your applications. For example, when we called `Console.WriteLine` earlier, we were calling a method from the `System.Console` class. For a more in-depth overview, you can read up on the .NET Class Library in the [.NET documentation](https://docs.microsoft.com/dotnet/standard/class-library-overview).
