Hi,

I am on Mac, using Xamarin Studio, trying to install Umbraco using NuGet.

It seems that somehow in the installation of UmbracoCms.Core package a Microsoft.AspNet.Mvc 5.2.3 is installed (as this at the time of writing is the latest version?). That is a problem for current version of Umbraco (7.2.8) which is not ready for Mvc 5.

Here is the log from the Package Console:

> Adding UmbracoCms... Attempting to resolve dependency 'UmbracoCms.Core

I have tried to start from different project types, including Mvc and Empty project. I have tried to manually remove any Mvc packages and references, but seem to end up with the same result.

Anyone out there who can help?
