I'd like to use .NET in some PowerShell scripts I'm about to write -- how do I know/declare which version of .NET I'm dealing with when these scripts run?

And is it possible to choose against which version of .NET my script will run?

version powershell .net

This is an old thread, and the answer I am going to post now will not work for .NET versions from from before circa 2017.

There is a new FrameworkDescription property.

Try:

[System.Runtime.InteropServices.RuntimeInformation]::FrameworkDescription

Note, however, on some versions of Windows PowerShell (not sure about newer PowerShell 6 and 7 etc.) there are two different types System.Runtime.InteropServices.RuntimeInformation in different assemblies! And only one of them has the property. So you must qualify:

[System.Runtime.InteropServices.RuntimeInformation, Microsoft.Powershell.PSReadline]::FrameworkDescription   # does not exist
[System.Runtime.InteropServices.RuntimeInformation, mscorlib]::FrameworkDescription   # good
