Determine .NET Framework version for dll

by

In PowerShell you can use the following to get the target runtime:

$path = "C:\Some.dll"
[Reflection.Assembly]::ReflectionOnlyLoadFrom($path).ImageRuntimeVersion

I adapted this to PowerShell from Ben Griswold’s answer.

If you want to know the target framework version specified in Visual Studio, use:

$path = "C:\Some.dll"
[Reflection.Assembly]::ReflectionOnlyLoadFrom($path).CustomAttributes |
Where-Object {$_.AttributeType.Name -eq "TargetFrameworkAttribute" } | 
Select-Object -ExpandProperty ConstructorArguments | 
Select-Object -ExpandProperty value

You should get something like

.NETFramework,Version=v4.5.2
