DNVM clean up with update-self, uninstall and the like

This post is about upgrading and managing dnvm and runtimes installed on your machine.

Short Story

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}"

first install of dnvmto get some dnx

dnvm

lists the commands you can call with dnvm to manage your runtimes

dnvm update-self

will update your version manager tool (dnvm itself, not the runtimes)

dnvm list

will list all installed runtimes

dnvm uninstall  1.0.0-beta8 -arch x64 -r clr

unintsall a runtime version

dnvm upgrade -r coreclr -arch x64

upgrades a version already installed

Long Story

> which version is installed on your machine

Currently I have dnvm v1.0.0-beta5-10368 installed on my machine. to check this, just open a command prompt and type dnvm

dnvm-help

By the way, if nothing is installed on your machine, just type the following in a command prompt :

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}"

> upgrade dnvm self

Now update dnvm version to the latest version:

dnvm update-self

this results for me in version v1.0.0-rc2-15546 which is the latest when writing this post

dnvm-update-self

> dnvm list, install, upgrade and uninstall
dnvm list

will show all runtimes installed on your machine. you can uninstall them by issuing the following

dnvm uninstall  1.0.0-beta5 -arch x64 -r coreclr

and that for each version installed in each arch and in each runtime

so I had to issue a long list of commands :

...
C:\Temp>dnvm uninstall  1.0.0-beta8 -arch x86 -r coreclr
Removed 'C:\Users\a406775\.dnx\runtimes\dnx-coreclr-win-x86.1.0.0-beta8'

C:\Temp>dnvm uninstall  1.0.0-beta8 -arch x86 -r clr
Removed 'C:\Users\a406775\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta8'

C:\Temp>dnvm uninstall  1.0.0-beta8 -arch x64 -r clr
Removed 'C:\Users\a406775\.dnx\runtimes\dnx-clr-win-x64.1.0.0-beta8'
...

use dnvm upgrade to upgrade your dnx version to the latest:

dnvm upgrade -r coreclr -arch x64
