Linux Installation warning that dotnet version is wrong

[knoxyca]

Install script failing in multiple ways on Linux.

Having the latest dotnet isntalled, gives an error that you're not on the expected version.

PS /home/corbob/Jupyter-PowerShell> ./Install.ps1 -KernelFolder ~/.jupyter/kernel                                                                                        
WARNING: 
            The currently installed 'dotnet' (.NET Command Line Tools) is not the expected version.

            Installed version: 2.0.0-preview2-006127
            Expected version: 2.0.0-preview1-005977

            If your version is older, you PROBABLY cannot run the 'PowerShell (Core)' kernel.

            Get the latest version from https://www.microsoft.com/net/core/preview
            

            
/usr/bin/mkdir: invalid option -- 'P'
Try '/usr/bin/mkdir --help' for more information.

This doesn't seem to stop the installation, but it is a warning that comes up.

Yeah. Preview2 just came out last week...

I'll upgrade my dev box to Preview2 tonight and change that warning to be the other way around ...

I'm closing this -- the mkdir error was handled elsewhere, and this warning is going to stick around -- the new "semantic" versions are nigh impossible to compare.
