A Microsoft Doc has a table for required versions of .NET Framework for PowerShell versions 3.0 to 5.1: https://docs.microsoft.com/en-us/powershell/scripting/windows-powershell/install/windows-powershell-system-requirements?view=powershell-7#microsoft-net-framework-requirements

After installing PowerShell 7.0 on a fresh Linux instance that didn't have PowerShell or .NET, I noticed that PS cmdlets worked normally. When I looked at the .NET runtimes, none were listed. When I ran $PSVersionTable it didn't list the CLR, instead the following:

PS /home/ubuntu> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      7.0.3
PSEdition                      Core
GitCommitId                    7.0.3
OS                             Linux 5.3.0-1035-aws #37-Ubuntu SMP Sun Sep 6 01:17:09 UTC 2020
Platform                       Unix
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1
WSManStackVersion              3.0

This generated a few questions:

  • Is PowerShell 7.0 and 7.1 (currently being developed) considered a "self-contained" published .NET Core applications?
  • Does PowerShell 7.0 contain an self-contained/embedded version of .NET Core 3.1?
  • Will PowerShell 7.1 contain an self-contained/embedded version of .NET 5.0?
  • If you install other versions of .NET Core or .NET (such as .NET 6.0 - when released) would that have an affect on 7.0 or 7.1, or would always use the self-contained/embedded version?

I understand there is a relationship between PowerShell and .NET, but I can't locate the details via Google. I was able to setup a fresh Linux instance that didn't have PowerShell or .NET, and then only installed PowerShell. PS cmdlets worked normally. When I looked at the .NET runtimes, none were listed.

Questions:

  • What is the relationship/mapping between PowerShell and .NET?
  • Is there a document that shows the mapping?
  • Is you have more than one .NET runtime installed which one is used by PowerShell?

====================================

UPDATE

I created a follow-up question based on the answer below: PowerShell 7.0 / 7.1 and .NET runtimes
