Get a list of installed .NET versions on (remote) Windows computers.
As of 2019-06-18 versions up to .NET 4.8 are supported/detected. It's based on the information in this article: https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed
Blog documentation (I'm too lazy to duplicate here): https://www.powershelladmin.com/wiki/List_installed_.NET_versions_on_remote_computers
It's published to the PowerShell Gallery, so you can install/inspect/download with Install-Module, Find-Module and Save-Module. Link: https://www.powershellgallery.com/packages/DotNetVersionLister/
Example installation for your user only:
Install-Module -Name DotNetVersionLister -Scope CurrentUser #-Force
Example use:
Get-STDotNetVersion
and
Get-STDotNetVersion -ComputerName server1, server2, server3
or
Get-STDotNetVersion -ComputerName server1, server2, server3 -PSRemoting
Example output:
Get-STDotNetVersion -NoSummary
ComputerName : localhost
>=4.x : 4.6.2
v4\Client : Installed
v4\Full : Installed
v3.5 : Not installed (no key)
v3.0 : Not installed (no key)
v2.0.50727 : Not installed (no key)
v1.1.4322 : Not installed (no key)
Ping : True
Error :
The command/function name used to be Get-DotNetVersion in versions before v3 of the module. This is aliased if the command does not currently exist in the PowerShell session, but you have to either run Get-STDotNetVersion first to load it, as auto-load for Get-DotNetVersion does not work - or you can simply Import-Module -Name DotNetVersionLister first, as we had to on PowerShell v2.
NB! Note made 2019-02-15: I got some issues with publishing right now, so the version in the PowerShell gallery is still 2.2.6. I will direct my mental energy in such a way that the module is eventually published when the energy patterns align. 2.2.6 uses Get-DotNetVersion not Get-STDotNetVersion, while the version you can git clone here is the new one.
At around 5 AM on a sleepless night January 27, 2020, the energy patterns aligned. The new v3.0.1 module is published. Let me know if I broke anything.
