Get .NET Framework version installed on Windows using PowerShell

How to find out installed version of .NET Framework with PowerShell

Finding out installed .NET Framework version on the host Windows OS is not an everyday job, but when it comes to deployments of the .NET application it is needed to check if the host supports targeting .NET Framework version.

Starting from .NET Framework 4.5, Microsoft is storing .NET Framework version as a key in registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\Release

Regedit -ffx

Depending on the key value, you can determine the version f the .NET Framework installed

.NET Framework VersionRegistry key value
.NET Framework 4.5 378389
.NET Framework 4.5.1 378675
.NET Framework 4.5.2 379893
.NET Framework 4.6 393295
.NET Framework 4.6.1 394254
.NET Framework 4.6.2 394802
.NET Framework 4.7 460798
.NET Framework 4.7.1 461308
.NET Framework 4.7.2 461808

Following this enumeration, it is easy to write PowerShell script for reading and retrieving .NET Framework version based on the value of the registry key value entry

$netRegKey = Get-Childitem "HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full"
$release = $netRegKey.GetValue("Release")
$releases =@(
@{id="378389";value=".NET Framework 4.5"},
@{id="378675";value=".NET Framework 4.5.1"}
@{id="379893";value=".NET Framework 4.5.2"},

    @{id="461308";value=".NET Framework 4.7.1"}
