Asp.NET MVC 5 DNX core giving error on nuget package I installed

I am new to MVC 5 and I have installed a Nuget package called Dapper which is a micro ORM. The problem I am having is that DNX Core 5.0 is giving this error

Severity    Code    Description Project File    Line    Suppression State
Error   NU1002  The dependency Dapper 1.42.0 in project Exo does not support
 framework DNXCore,Version=v5.0.c:\users\iggy\documents\visual studio   2015\Projects\Exo\src\Exo\project.json

Is there anyway I can fix this? because I know that both DNX Core and DNX 4.5.1 are meant to run side by side. I can't compile because it is stating that I have an error.

In case the picture is hard to see basically the DNX core has a yellow ribbon on it because of the error and DNX 4.5.1 is fine. Any suggestions would be great...
