Install failed. Rolling back... Could not install package 'Microsoft.Owin.Security 2.0.2'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author.

on also in my web.config line <httpRuntime targetFramework="4.5"/> says

the targetFramework attribute is not allowed.

and my web.config is

    <?xml version="1.0"?>
