Here at the university have we developed an extension to SCCM which automates the tasks of importing and deploying applications written with PSADT. People are welcome to check it out.
It is written i PowerShell and Xaml. To run powershell silently we have also developed an small c# application which just starts powershell without opening an console. You find it here:
We hope this could be useful to other users of this great tool PSADT
