Create a Custom Detection Script for ASP.NET Core Runtime 7.0 (PowerShell)

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 ASP.NET Core Runtime 7.0 using PowerShell.

How to Create a Custom Detection Script for ASP.NET Core Runtime 7.0

ASP.NET Core Runtime 7.0 x86 (Registry Detection Method)

Install the version of ASP.NET Core Runtime 7.0 x86 you want to deploy on a test box or VM

  - ASP.NET Core Runtime 7.0 Install and Uninstall (PowerShell)
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 ASP.NET Core Runtime 7.0 x86 (Registry Detection Method)
$ASPNET7x86 = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -like 'Microsoft ASP.NET Core 7.0*(x86)' -and $_.UninstallString -notlike 'MsiExec.exe*' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$ASPNET7x86.DisplayVersion
$ASPNET7x86.PSChildName

## Create Text File with ASP.NET Core Runtime 7.0 x86 Registry Detection Method
$FilePath = "C:\Windows\Temp\ASP_NET_Core_7_x86_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($ASPNET7x86.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($ASPNET7x86.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($ASPNET7x86.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath

Click Run Script (F5)
A text file will open with the ASP.NET Core Runtime 7.0 x86 Detection Method script required to detect the current version of ASP.NET Core Runtime 7.0 x86 that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{4c9099e6-cfc0-4ee8-95d9-ef1ee02dc4ae}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{4c9099e6-cfc0-4ee8-95d9-ef1ee02dc4ae}' -Name DisplayVersion -ea SilentlyContinue) -ge '7.0.0.22303') {
Write-Host "Installed"
}

Copy the ASP.NET Core Runtime 7.0 x86 Detection Method script content into the Custom Detection Rules (Script)
