Can not install NuGet package

Question

I am trying to add the Unity package to my solution, but I keep receiving the listed message:

Attempting to resolve dependency 'Unity (≥ 3.5.1404.0)'.

'Unity' already has a dependency defined for 'CommonServiceLocator'.

Any Idea how to fix this?

Which version of nuget PM you are using, older version of nuget can be problem here. — Rao Ehsan, Apr 25 '14 at 07:21

After updating NuGet, I uninstalled and re-installed the offending package and then it worked for me – Peter Kerr Aug 30 '16 at 13:52

You are using Higher version .Net framework. And you are adding Lower version of Unity in to it.

your Application Framework will be above 4.0 or 4.0 and you are adding Unity frame work which is of .net frame 3.5.
