In order to install .NET Core on Ubuntu, you need to first set up the apt-get feed that hosts the package you need.
sudo sh -c 'echo "deb [arch=amd64] https://apt-mo.trafficmanager.net/repos/dotnet-release/ xenial main" > /etc/apt/sources.list.d/dotnetdev.list' sudo apt-key adv --keyserver apt-mo.trafficmanager.net --recv-keys 417A0893 sudo apt-get update
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
Let’s initialize a sample Hello World application!
mkdir hwapp cd hwapp dotnet new
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
You now have .NET core running on your machine!
