Issue
I would like to install the current version Core 1.0. Currently the RC2 version is installed. The instruction on the official website are:
Before you start, please remove any previous versions of .NET Core from your system.
But I don't know how and I can't find nothing from Microsoft like for example here.
I found this script... but my Linux skills are not great and I won't make it worst.
Solution
Sometimes it can be so simple! In order to remove the previous installation, simply remove the dotnet folder from where you installed it on disk.
Big Thanks to Zlatko Knezevic
