How to add a PSCmdlet or PSSnapin to hosted Powershell runtime without installing the snapin

My scenario is as follows.

• I am uploading my dll through web UI.
• I am hosting a PowerShell runspace in an ASP.NET application.
• I The DLL contains the PSCmdlet and woul开发者_如何学编程d like to make use of it.
• The PSCmdlet only needs to be accessible within the hosted runspace and does not need to be used in any external scenario.
• The application does not have access to the windows registry as it runs with limited privileges, so I cannot install the PsSnapin.

Is it possible for me to use the commandlet without going through the installation process?

Import-Module ‹path-to-dll›

add a -passthru to get the PSModuleInfo reference which describes the module.
