Creating a new program using .NET Core C# with Example

First install the .NET Core SDK by going through the installation instructions for the platform of your choice: 
Windows 
OSX 
Linux 
Docker 
After the installation has completed, open a command prompt, or terminal window. 
1. Create a new directory with mkdir hello_world and change into the newly created directory with cd 
hello_world. 
2. Create a new console application with dotnet new console. 
This will produce two files: 
hello_world.csproj 
 
 
Exe 
netcoreapp1.1 
 
 
Program.cs 
using System; 
 

namespace hello_world 
{ 
class Program 
{ 
static void Main(string[] args) 
{ 
Console.WriteLine("Hello World!"); 
} 
} 
} 
3. Restore the needed packages with dotnet restore. 
4. Optional Build the application with dotnet build for Debug or dotnet build -c Release for Release. dotnet 
run will also run the compiler and throw build errors, if any are found. 
5. Run the application with dotnet run for Debug or dotnet run 
.\bin\Release\netcoreapp1.1\hello_world.dll for Release.
