Running a powershell command in C# errors with, “Cannot invoke this function because the current host does not implement it”

Question

I have an application that I use to run Exchange Powershell commands inside C# code like below. This is an example of the relevant lines I use to run the powershell command

Answer 1

If that command would normally prompt for confirmation then you will need to either:

• Set -Confirm:$false as a parameter (and possibly -Force as well)
• Set $ConfirmPreference = "None" before calling Set-Mailbox (and possibly -Force too)
• Create a Host and implement the Confirm functionality ;-)
