adding a powershell snappin asynchronously

I am writing a powershell based application using winforms which is intended to deploy servers using SCCM. One of the functions the application provides is the creation of virtual machines using the VMware PowerCLI pssnapin. The problem is that the when the app is run, the add-pssnapin takes around 50 secs to complete, during which time it looks like the app has hung.
I've tried using start-job to add the snapin, but it doesn't seem to work - any calls to the powercli cmdlets fail.

Would really surprise me if anyone came up with something. You need the imported cmdlets, so how should that work? Remember - the snap-in changes your PS environment ...

I'm aware of the fact that the snapin changes the environment, what I'm trying to do is find a way to load it without having the application/script take a massive pause as it loads.

Didn't try, but maybe it works if you create a new session with start-job, importing the PowerCLI snap-in, and then Import-PsSession as soon as the job is ready again. Importing a session should work much faster than importing a module (the first time).

Another way is to start the whole application with a correct PowerCLI session configuration. You will have the delay when starting the application, though.

Tried your suggestion but ironically it took longer to import the session than it did to add the snappin

Sad. I was afraid of that. Importing a session involves creating proxy calls, which puts more workload on it overall.
Are you able to use the session configuration from start, as PowerCLI does? What I refer to is something along:
powershell.exe -psc "C:\Program Files\VMware\Infrastructure\vSphere PowerCLI\vim.psc1" -noe -c ". \"C:\Program Files\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1\""
