Combining a key and certificate into a .pfx file

If you want to use SSL with your site in Azure you need to have a .pfx file.

We Apache you most likely have a certificate and a private key. I am using certificate from Letsencrypt.

Using openssl you can generate the .pfx file like this:

openssl pkcs12 -export -out /tmp/certificate.pfx
-inkey /etc/letsencrypt/live/yourdomain.tld/privkey.pem
-in /etc/letsencrypt/live/yourdomain.tld/cert.pem
-certfile /etc/letsencrypt/live/yourdomain.tld/chain.pem

Replace yourdomain.tld with your actual domain name.
You will be asked for a password to protect the .pfx file

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.

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

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

Let’s initialize a sample Hello World application!

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!

You now have .NET core running on your machine!
