Hosted PowerShell cannot see Cmdlets in the same Assembly

Question

I\'m trying to run PowerShell scripts from my C# code, that will use custom Cmdlets from the assembly that runs them. Here is the code:

Answer 1

You do need to register your cmdlet before you can use it in a Powershell session. You'll generally do that by way of a Powershell Snap-In. Here's a high-level overview of the process:

• Create custom cmdlets (you've already done this part)
• Create a Powershell Snap-in which contains and describes your cmdlets
• Install the new Snap-in on your system using Installutil
• Add the Snap-in to a specific Powershell session using Add-PSSnapin

There are a couple useful articles on MSDN that explain the process pretty thoroughly:

• Developing with Windows PowerShell
• How to Create a Windows PowerShell Snap-in

There's also a 2-part series on ByteBlocks that discusses writing custom cmdlets. That series may be your best bet, since you seem to have done the equivalent of part 1 already. You may be able to just use part 2 as a quick reference and be good to go.
