Add the dotnet apt-get feed
In order to install .NET Core on Ubuntu, you need to first set up the apt-get feed that hosts the package you need.

Install .NET Core SDK
Before you start, please remove any previous versions of .NET Core from your system by using this script.
sudo apt-get install dotnet-dev-1.0.0-preview2-003121
Initialize some code

mkdir hwapp cd hwapp dotnet new
Run the app
The first command will restore the packages specified in the project.json file, and the second command will run the actual sample:
dotnet restore dotnet run
And you’re ready!
