My project needs to target .NET 3.5, but when I add a reference to Accord.Video.FFMPEG from the net35 folder I get this warning:

The primary reference "Accord.Video.FFMPEG, Version=3.3.0.0, Culture=neutral, PublicKeyToken=fa1a88e29555ccf7, processorArchitecture=x86" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.

Can this be fixed?
