What is the difference between Add-PSSnapin and Import-Module in PowerShell?

In the end, both seem similar to the same result.

Which one is recommended?

Answer 1

PsSnapins is an old way (existing inPowerShell V1) to add CmdLet or Providers (but still in use)

• They need to register (using the installutil.exe tool)
• These are assemblies written in the same .NET language.

Modules is a new way (added in PowerShel V2) to add CmdLet or providers

• They just need to be attached to the file system (see $ env: psmodulepath)
• They can be scripts written in PowerShell (CmdLet only) or assemblies for CmdLet and Providers written in the same .NET language.

• There is an explicit form in it that allows you to specify a lot of information about the creator, as well as dependencies on PowerShell versions, Framework versions, or other versions of modules or assemblies.

  I think you can use the module if you do not need to support existing PowerShell V1 computers.
