Hi,

I have a .net project that is built upon powershell project template.
The project contains cmdlets and snapin to register them.

I want to be able to change powershell configuration file (that resides in powershel home directory) at run time and use the new settings without having to restart powershell session.

How do change configuration file on the fly and use it immediately at the current session?

#You can use these commands

#Put your code in your profile
"Write-Host 'Test'" | Set-Content $profile

#After that run your profile
& $profile

First of all, you should dot-source your profile, not call it, so you need:
. $Profile

But it's a mistake to think that changing the profile and then executing it is the same as changing it and launching a new instance of PowerShell, because you're not clearing out what has already been done, you're merely layering the effects of a new profile on top of it. As long as you're aware of the difference, dot-sourcing your profile should be ok.
