Our company has some computers with an older version of Powershell as not all machines are allowed to receive certain updates due to dependencies. I am using the nuget-extension Microsoft.PowerShell.5.1.ReferenceAssemblies on computers with Powershell 5.1 and Microsoft.PowerShell.5.0.ReferenceAssemblies on computers with Powershell 5.0 in my C# CmdLet Project however I can not use both together.
How can I support multiple Powershell versions in my C# CmdLet project?
Use the PowerShellStandard.Library package to create modules (cmdlets) that run across multiple versions and even editions; i.e., they run on both Windows PowerShell and PowerShell [Core].
Use version 3 to create cmdlets that run on PowerShell version 3 and later.
3.0.0-preview-02, from 2018 - I don't know why.Use version 5.1 to create cmdlets that run on PowerShell version 5.1 and later.
See the PowerShell Standard GitHub repo for more information.
Note:
Said PowerShellStandard.Library package is meant for developing code that runs from inside PowerShell on a given machine; that is, it needs an existing PowerShell installation.
By contrast, the following packages allow you to bundle PowerShell with your application:
Microsoft.PowerShell.SDK - for building PowerShell Core applications, based on .NET Core (cross-platform).
Microsoft.PowerShell.5.ReferenceAssemblies - for building Windows PowerShell applications, based on the .NET Framework (Windows-only)
