Tasks to create an IIS application pool and web site on Windows 10 with PowerShell and Visual Studio Code:

• Install the Visual Studio Code plugin PowerShell 0.6.2
• Create a file iis.configuration.ps1 in Visual Studio Code:

# Note: When run with the Visual Studio Code PowerShell debugger, make sure you use the "x64" debugger,   
#       else you will get an error: New-WebAppPool : Cannot retrieve the dynamic parameters for the cmdlet.
Import-Module WebAdministration

# Create application pools 
New-WebAppPool -Name "myapp.localhost" -Force

# Create websites  
New-Website -Name "myapp.localhost" -Port 80 -HostHeader "myapp.localhost" -ApplicationPool "myapp.localhost" -PhysicalPath "c:\projects\myapp\web" -Force

• Create a launch.json in the same folder as the iis.configuration.ps1:

{   
    "version": "0.2.0",   
     "configurations": [  
        {   
            "name": "PowerShell",   
            "type": "PowerShell",   
            "request": "launch",   
            "program": "${workspaceRoot}/iis.configuration.ps1",   
            "args": [],   
            "cwd": "${workspaceRoot}/iis.configuration.ps1"   
        },   
         {   
            "name": "PowerShell x86",   
            "type": "PowerShell x86",   
            "request": "launch",   
            "program": "${workspaceRoot}/iis.configuration.ps1",   
            "args": [],   
            "cwd": "${workspaceRoot}/iis.configuration.ps1"   
        }   
    ]   
 }

Now you can debug / run the iis.configuration.ps1 file, by hitting F5, make sure you selected “PowerShell” and not “PowerShell x86” on the debug tab:
