    You'll need to add a assembly redirect for NewtonSoft.Json, as it's trying to use v6, but Umbraco ships with 7.7.9. 

            <dependentAssembly>
            <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-10.0.0.0" newVersion="10.0.0.0" />
        </dependentAssembly>
