System.Management.Automation.PowerShell不会从IIS返回Get-Website的结果

Question

We're using System.Management.Automation.PowerShell for executing PowerShell scripts.

Everything worked fine for many scenarios until we need to set some properties of a web site on IIS (ServerAutostart etc.).

We made a PS1 script which works as we expected, however, after execution via C#, it crashes. After some exploration, I extracted the problematic part:

PS1 script:

# Set execution policy
Set-ExecutionPolicy Unrestricted -Scope Process -Force
Set-ExecutionPolicy Unrestricted -Scope LocalMachine -Force
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force

# Import modules
Import-Module WebAdministration
Import-Module IISAdministration -MinimumVersion 1.1.0.0

# Getting IIS Sites
$iisSite = Get-IISSite

If ($iisSite)
{
    Write-Host "$($iisSite.Count) IISSites were found"
} 
else 
{
    Write-Error "IISSite was not found"
}

$webSite = Get-Website

# Getting Web Sites

If ($webSite)
{
    Write-Host "$($webSite.Count) WebSites were found"
} 
else 
{
    Write-Error "WebSites was not found"
} 

If I run it via Windows PowerShell ISE , it works perfectly:

23 IISSites were found
23 WebSites were found

However, if the script is executed via C# and System.Management.Automation.PowerShell , it returns following:

23 IISSites were found
WebSites was not found

What is the difference? Why Get-IISSite works and Get-Website not? Permissions? Missing modules?

To set WebSite properties, we need to work with it via Get-WebSite . Unfortunately, it seems to be a conceptual problem...

Thank you for your help...

Problem was caused by prefering 32-bit mode in the Build tab in 64-bit system.

Prefering 32-bit mode

After uncheck, everything works well.
