Problem
I had a funky installation of Visual Studio. Everything seemed to be working but when I came to install the Microsoft .Net Core 1.0.0 VS 2015 Tooling it refused to install:
Repeated attempts to repair or reinstall Visual Studio 2015 Enterprise just wasn’t getting anywhere and I wasn’t in a position to flatten the machine and start again. What was I to do?
Solution
I managed to run the installer and force it not to check Visual Studio using a command line switch:
ukafr02@UKSTOL0079 C:\Users\ukafr02\Downloads $ DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1
Happy days!
