Another short tip
When cloning a project for use on Mac and Xamarin Studio that was originally created in Visual Studio on PC, you might encounter a "Could not find part of the path" build error.
It's simply just some missing folders.
For example, if the error looks something like this:
Error: Could not find a part of the path "/Users/johankarlsson/Projects/TheProject/TheProject.Core/obj/Debug/TheProject.Core.csproj.FilesWrittenAbsolute.txt".
