Create a Custom Detection Script for Microsoft .NET SDK 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 Microsoft .NET SDK 7.0 using PowerShell.

How to Create a Custom Detection Script for .NET SDK 7.0

Microsoft .NET SDK 7.0 x86 (Registry Detection Method)

• Install the version of Microsoft .NET SDK 7.0 x86 you want to deploy on a test box or VM
  • Check out the following posts for further details
    • Microsoft .NET SDK 7.0 Silent Install (How-To Guide)
    • Microsoft .NET SDK 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 Microsoft .NET SDK 7.0 x86 (Registry Detection Method)
$NETSDK7x86 = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -like 'Microsoft .NET SDK 7.0*(x86)' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$NETSDK7x86.DisplayVersion
$NETSDK7x86.PSChildName

## Create Text File with Microsoft .NET SDK 7.0 x86 Registry Detection Method
$FilePath = "C:\Windows\Temp\Microsoft_NET_SDK_7_x86_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If(([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Windows\CurrentVersion\Uninstall\$($NETSDK7x86.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($NETSDK7x86.PSChildName)' -Name DisplayVersion -ea SilentlyContinue)) -ge '$($NETSDK7x86.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath

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

Example:

If(([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Windows\CurrentVersion\Uninstall\{335f3fab-874a-49e8-8b92-5bdabda52956}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{335f3fab-874a-49e8-8b92-5bdabda52956}' -Name DisplayVersion -ea SilentlyContinue)) -ge '7.1.22.30718') {
Write-Host "Installed"
}

• Copy the Microsoft .NET SDK 7.0 x86 Detection Method script content into the Custom Detection Rules (Script)
• Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM)
  • https://docs.microsoft.com/en-us/mem/configmgr/apps/deploy-use/create-applications#bkmk_detect-script
• Microsoft Intune
