# Create and run simple C# console applications (Get started with C#, Part 2)
Your goal was to install and configure a development environment that meets your coding requirements for C#.
You've installed Visual Studio Code and a tour of the user interface demonstrated a logical layout that is consistent with industry standards. You were able to configure extensions that make Visual Studio Code an even more powerful tool for C# code development. You also installed the .NET SDK to provide compiler and runtime support, and support for .NET command line interface commands.
- Download and install Visual Studio Code
- Configure Visual Studio Code
- install the C# extension
- install the.NET Core SDK
- install the.NET Core runtime
- install the.NET Core command line interface
- install the C# language support for Visual Studio Code
- configure Visual Studio Code to use the.NET Core command line interface
- install the.NET SDK
- Create and run a simple C# console application
```
dotnet new console -o --name HelloWorld
```
- Build and run the application
```
dotnet build
```
- Run a C# console application
```
dotnet run
```
# The C# programming language allows you to build many types of applications, like:
- Business applications to capture, analyze, and process data
- Dynamic web applications that can be accessed from a web browser
- Games, both 2D and 3D
- Financial and scientific applications
- Cloud-based applications
- Mobile applications
In this module, you'll:
- Write your first lines of C# code.
- Use two different techniques to print a message as output.
- Diagnose errors when code is incorrect.
- Identify different C# syntax elements like operators, classes, and methods.
# C# is
- C# is a case-sensitive
- Use double quotation marks to define a string
```
Console.WriteLine(''Hello World!'');
```
Console part is called a class
Classes "own" methods; or you could say that methods live inside of a class
WriteLine() part is called a method
The parentheses are known as the method invocation operator
the semicolon is the end of statement operator
The difference between Console.Write and Console.WriteLine
- Console.Write is used to print a message without a new line
- Console.WriteLine is used to print a message with a new line
- syntax: rules for writing C# code is called syntax.
