Determine framework (CLR) version of assembly

Question

From the command line (or by any means really), how can I determine which CLR version a .NET assembly requires?

I need to determine if an assembly requires 2.0 or 4

Answer 1

I use ILSpy as a replacement for Reflector. If you open the assembly in ILSpy, you can see, for example:

[assembly: TargetFramework(".NETFramework,Version=v4.6.2", FrameworkDisplayName = ".NET Framework 4.6.2")]
