Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Azure Functions Core Tools using PowerShell.
How to Create a Custom Detection Script for Azure Functions Core Tools
Azure Functions Core Tools (File Detection Method)
- Install the version of Azure Functions Core Tools you want to deploy on a test box or VM
- Check out the following posts for further details
- Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
- Copy the following code into the Windows PowerShell ISE
## Check for Azure Functions Core Tools (File Detection Method)
$AzureFuncCliExe = (Get-ChildItem -Path "C:\Program Files\Microsoft\Azure Functions Core Tools\func.exe" -ErrorAction SilentlyContinue)
$AzureFuncCliExe.FullName
$AzureFuncCliPath = $($AzureFuncCliExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($AzureFuncCliExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion
## Create Text File with Azure Functions Core Tools File Detection Method
$FilePath = "C:\Windows\Temp\Azure_Functions_Core_Tools_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$AzureFuncCliPath`",`"`${Env:ProgramFiles(x86)}\$AzureFuncCliPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
- Click Run Script (F5)
- A text file will open with the Azure Functions Core Tools Detection Method script required to detect the current version of Azure Functions Core Tools that is installed on the device you are running the script from.
Example:
If([String](Get-Item -Path "$Env:ProgramFiles\Microsoft\Azure Functions Core Tools\func.exe","${Env:ProgramFiles(x86)}\Microsoft\Azure Functions Core Tools\func.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "4.0.4785"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
- Copy the Azure Functions Core Tools Detection Method script content into the Custom Detection Rules (Script)
- Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM)
- Microsoft Intune
Azure Functions Core Tools (Registry Detection Method)
- Install the version of Azure Functions Core Tools you want to deploy on a test box or VM
- Check out the following posts for further details
- Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
- Copy the following code into the Windows PowerShell ISE
## Check for Azure Functions Core Tools (Registry Detection Method)
$AzureFuncCli = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Azure Functions Core Tools' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$AzureFuncCli.DisplayVersion
$AzureFuncCli.PSChildName
## Create Text File with Azure Functions Core Tools Registry Detection Method
$FilePath = "C:\Windows\Temp\Azure_Functions_Core_Tools_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($AzureFuncCli.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($AzureFuncCli.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($AzureFuncCli.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
- Click Run Script (F5)
- A text file will open with the Azure Functions Core Tools Detection Method script required to detect the current version of Azure Functions Core Tools that is installed on the device you are running the script from.
Example:
If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{B11C4E91-77C7-447E-82A9-2616DBFF95E2}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{B11C4E91-77C7-447E-82A9-2616DBFF95E2}' -Name DisplayVersion -ea SilentlyContinue) -ge '4.0.4785') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
- Copy the Azure Functions Core Tools Detection Method script content into the Custom Detection Rules (Script)
- Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM)
- Microsoft Intune
