Get-FrameworkVersion.ps1 displays a list of all .NET Framework versions installed on a computer. While other scripts perform similar functionality, those I found were not well-behaved when they found an unknown version. Thus, the genesis for this version. Operation is simple:
PS C:\scripts> .\Get-FrameworkVersion.ps1 v2.0.50727 2.0.50727.4927 SP2 v3.0 3.0.30729.4926 SP2 v3.5 3.5.30729.4926 SP1 v4 Client 4.7.02556 Full 4.7.02556 v4.0 Client 188.8.131.52 Current .NET Framework version: 4.7.1 on Windows 10 (4.7.02556 = release 461308) PS C:\scripts>
I have posted the script on the TechNet Gallery: Display a list of all .NET Framework Versions installed on a computer.
The script is small enough that you can easily use it inside an Invoke-Command to execute on another computer. I will add native remote functionality in the next version.
