Despite of being old, AForge is mature, stable and fulfill very well its job in server production code.
However, I noticed that the AForge that comes with NuGet is compiled with NET 2.0. I am using .NET 4.5.2.
Because I need AForge for a client application that will process Video streams, I wonder if there any performance penalty in general when I use referenced assemblies that are compiled with older .NET releases.
